From YouTube: .NET Core Design Reviews: System.IO.Pipelines

Description

We'll take a look at the new pipeline APIs David Fowler has created for use in ASP.NET Core.

For notes, take a look https://github.com/dotnet/apireviews/tree/master/2017/07-11-System.IO.Pipelines.

A

Let's go back to it all right, wow I'm impressed so.

B

mmm Maybe you should shoot up a code sample that help like everyone.

C

B

The thing so maybe pull up corporates lab I, look like a unit test will be the easiest way to peddling your thing.

D

Otis ping pong thing.

B

B

Samples no I mean.

C

B

Factory, creating a pipe the bullfights look around system. They are that thun missing a super factory.

B

B

B

That shows some consumption. um Okay, so maybe put the the API side by side with a sample. So we can look at the types and sounds like your PIN thing. So the first thing is Darth is the I pipe factory? It's Argus the pipe battery. That's when I see career pipe.

B

The names are kind of bad. This pipe is not looking names, hi, Brandon, so she's.

C

Gonna suck super.

B

I love, ya, I guess I should um so a pipe is basically think of it, like a a channel right sold just twice to a pipe there's and there is someone that by right, there's some that reads alright. So today, if you look at like a stream, that's juice kind of it's kind of an obstruction that you kind of implement. Reading right in this type model, you create a pipe Somerset's in Minnesota kind of the basic vertebrae, um the pipe itself odd memory.

B

So when you call read your seat pocket buffer, you don't pass in one when you, when you wanna write a buffer. It's the same thing applies. You actually allocated data from the piper, so you say: cranium pipe LTS, these things in the pipe and you call it right and then the reader gets data whenever the printer press it to the actual pipe, that's kind of the bid, the basic verdict so and types to get a pipe. You use a pipe artery.

B

So you carry one of these guys for the buffer pool and you say: create pipe.

B

So the reason for having this, rather than just do it up this for the pool pitbull yeah, so my project is kind of the route through the universe. So this guy's, like the pool or whatever it has you call clay pipe. This guy gives you an I pipe back, which has our reader and writer and those guys kind of married to the same the same like inner structure. So when you call right on the right side, we really can be seen a bit so.

C

You said that the reason for the factory is the pool, but you could just pass a pool to quiet, constructor yeah you could so. Why would we not do it um because.

B

You can I pipe back today, this an abstraction, it's not the concrete implication and that pipe could be implemented with any any kind of thing. um We could expose pipe and have you pass in the pool directly, but it takes a bunch of parameters so.

C

B

So yes, in the beginning, we had idea because then you kidding you up, but we kind of end up with a pocket because it can make kind of married to the hole bump. Originally it was like toss hatchery create toss. This isn't like a peipus is there's nothing that makes italy require tip to dia yeah yeah. um So what is a five? An interface?

B

What do you interface.

C

B

um It could be nunchakus classes, there's no there's no reason it has me in place. One benefit is that you can actually implement one on at the scene type if you want to decorate a pipe. So if you had a type that was like, if you had um a stream, let's say I had foo foo stream.

B

It was this generating could also be a pipe I can make it do things mastering things again, the same type of code having to bit you can to businesses. I. Think.

C

That's an example, something we actually.

B

Thought our thank you thing yeah. So how does this relate to those pipes? Doesn't well it's a fun name. Why isn't this for pipeline? So the so the reason I change the name, because it makes more sense. So the pipe is like one of the things the pipeline. It's like a bunch of pipes chained together. So if you had like no one other guy here, you could do this right right really see below this pipeline, and this is this is the pipeline, but individual things you ready to reach from our pipes.

B

The first name is channels, then there's a bingo channels, that's kind of not shifted, I'm kind of we're for worried that you get confused channels. There's a thing called pipes that ship I know, but the thing anywhere else, though, the other day I barely caught fire. We had rooms. We had like weird like rivers, streams, but conceptually it's the same as with those breaks. Just I, don't understand how you how you explain this. That's gonna, be one of the very first questions you get. Is it like? We have pipes yeah.

B

This is in process for one I, alright, so it's in process it I. Think of it have a very low level of abstraction. That is a producer/consumer white pump. So all it is, is you can write bison review ice through it in memory channel? Are we considered a better screen like it's.

A

My extreme that Benes, like a pipe.

B

It's a stream to have ministers over there. Yes, yes,.

E

B

Like a data flow, then look at it took a bit of look acting Mary's Lalo's it. um Those kind of things if you guys are familiar, even tells channels the prototype. It has similar concepts, you have a you, create a channel that is either buffered and unbuffered or bounzer nothing on bonded and it has an in and an output. So in I think rights are, you know out and roots are in, and you write to one side and the consumer concerns from different side, and you can pass any up.

B

Of course, that's kind of the main idea of like how the whole thing put together in a factory you get a pipe back and you read and write Sims look at this sample. The sound was interesting, so this entire API was made for a couple of reasons. It tries to simplify common things. You do when you read bytes from a stream and I also try to minimize allocations per read and per right, so the whole goal is you allocate the pipe once and you can reuse the pipe, but every culture arena right does minimal allocations.

B

So, for example, in this, in this basic as a whole, you wait for data by calling read a sank on the input pipe you like a result, you can the data from the result. The check is kind of wonky, so you you have to check to see.

B

So the reason yes decorate the buffer is empty and resides completed is because the writer can write much data and then close the right side and then the reading will be consuming, and you don't want to finish just because the writer said I'm done see so to drain the the buffer completely. You can I want to check for if the writer is done and if the buffer is empty by there by the reader. So.

C

Why don't you provide the helper called? Is data available or something like this, where on the reading side, so instead of calling you know empty and not not empty and not completed, you say: do I have more data to consume on.

B

The on the reader itself or on the result like they got from there yeah.

C

Think about you know in this example, it would be in please no more data, so you would say if input, no more data than break in.

B

Place the buffer softer the buffer itself is that thing ice is main leaving you when you get the result back years ago. It's like a result, buried, um yeah, a result.

C

Non buzzer, but it.

B

C

B

The entire thing, instead of having you check both things, arguably that's more useful- that is completed yeah the phone yeah yeah, yes,.

C

A

True, so what time is it they're, like this party.

C

Here, Barbie.

B

Hover over the neighbors or not it's a result. So this is not natural. I've been expecting the one you're sort of like sorry yeah, so the input is a pipe reader and the Elfa is a pipe writer from.

E

The connection where's.

B

The pipe in this scenario, the pipe, is pretty much the connection you can ignore that for now pretend look the.

D

Connection is is very close. Yeah.

B

The reason the reason this thing isn't: okay, so okay, so you can tell me this is stupid in.

B

Duplex pie, so so in this model right, this is a single like side of the pipe right. So you can imagine for connections connection. You have two pipes offering an offer output right. So this is the input type.

B

This is your pipe and, depending on what on who you are you consume like 1/2, each site right the make sense. So if you're like it so imagine this was an application. There was an app and there was like a transport like sockets or whatever. The Sunkiss is producing data to the application.

B

So whenever a recent from the from the my socket, it writes to the applications in the pipe right, so the transport is pretty nifty, actually application it like when the application and wants to write it is the socket it writes to the applications of the pipe. So kind of this is the socket owns 1/2 the end, the pipe on one half of it, so we added I think called a pipe connection to represent full-duplex like a half-duplex like we could have made it bi pipe, but it it's the same interface.

B

But it's kind of to to any kid that it's not kind of one pipe, but we could have done. We could have made it the same. Jeweler and cylindric.

C

Pipes so I forgot it it's a pipe connection. Is that what it is yeah is the duplex yeah yeah.

B

And to be fair, we don't need different type, it's just that it made it obvious that this is a enzyme difference which is being clean, so the same closely that we call your ex-wife hilly.

D

Yeah yeah, but it shouldn't be the same because if you take I spy, an you expected, if you write the one side, you expect it to be readable.

C

D

The other set and it's making you say you would yep how could I get the.

B

B

Signature, the.

D

B

Sides of a non duplex pipe I guess.

B

Is kind of its kind of just because he you reduce the number of concepts you have one I pipe. The only thing is you can play a single point versus two ends of a different. You can admit I pipe being two different ends of the same leg: I think they need to be different. I, agree programs, they're, Samantha,.

A

Runway different.

B

How do you describe two types? I have the same signature bar different, sometimes I, guess exactly teenager, like I, have a question with the same label. Adjusts two different interfaces: you can yeah. The interests name is do anything, but it pretty.

C

Much is the same thing.

B

One I'll get so far: Oh crazy, alright yeah I tried to contents in my head, which is actually not that easy, so I think I think the base, if you ticularly anything, take away the fact that is a you can write out that interface for you just look at it. Yeah look at look at um I. Imagine right! Look at this is the guy first, oh, no, no, better yeah! They.

D

Actually, have.

B

Different names yeah! No, so if you were to look at the right side, you see that.

B

If so, I pipe has reader/writer kind of both sides, the same the same pipe and I look and bind output and they're both the same types on on the properties but they're different concepts, so that makes elicits now they do me. That seems like the exactly the same thing. It is so one the I pipe. If I write to the writer I can read it from the video. This is. This is I PI yeah, there's the graft operation.

A

This is a pipe connection yeah this.

C

Actually is, this is.

D

The reason this you've not right- that's right, oh yeah course it decides.

C

So this is connection.

C

There are four: there are basically four sockets I buy piss prima sockets at the end, I buy connection, has two sockets diagonal from two different parts. So.

B

You want to think what, as data flowing from the routed from the right to the to the.

E

Reader series and.

B

E

Wider got right on I pipe and later on, I can retrieve the data. Yes, my pipe connection, officially I'm talking to opposite ends. Yes,.

B

E

B

One is late: it versus one yeah, I, guess I'll get with the stream. Well, no! No! No! It's.

C

My eye socket versus so I pipe connection.

B

Is more like the street there's more like a duplex design, pipe connection, yeah, there's really no analog industry right pipe! No!.

E

You know it knows something since okay, nice I cannot reset my path. Connection.

B

Chris I shouldn't be on the I pipe. To be honest, it should be on the implementation she shouldn't be on the abstraction reset. Is there because of reuse, so in cash? So we want to reach the same pipe for a muffler class for Burke. So the end is reset thing. It really should be on the type of implementation on the interface, because the actual consumer doesn't care.

C

B

Factory gives you an interface and that's.

C

The same, unfortunately,.

B

That's how about to make it not so.

C

We can somebody collect those decisions. I think this one is who.

B

Think you know taking notes I'm trying to take, though I like.

C

B

Whole these should be never gonna, use it for audiences school acquire anywhere. That sounds perfect. Actually.

C

B

Else using wire like boost read with yes, there's a name, damn: okay, it's really met our credit, no okay! So, let's get through all the big concepts in being paid, so factory creates a pipe pipe has to NC right to a degree from it. The connection is different: zip duplex height, you have two girls who are either in writer.

B

So let's go through the reader and writer, I guess and on the interfaces most would have said it's the next yeah I begged me to render read it first, I'm, mostly writer, quick yeah right at first yeah, probably so, like I was saying before one of the main goals was to push push more management to the actual pipe itself, because it because eight minus all the memory of the pipeline, see you how it hits natural pipe itself see you allocate you passing the int.

B

That thing not really work very well, but you fascinate asking for some kind of size. You get that thing back. You can write into and then you call flush.

B

How's, the painting flush we can discuss, watch off what the writable buffer- yes, yeah, so think of it as like. You get a memory or condition of a thing that so the, but you can clearly this treatmen SS I. Guess you get a thing back, you right to it right to attorney called flush to make it go the actual and is it dead instead turn it back certify breaks, Ted, nice, Ted and that's an interesting design custom because you can't really kill it, but it's dead.

E

How many, how many concurrent allocation is support only one yeah, it's.

A

Single parameter, Nevada.

E

That always stayed on itself on the radar self. Let's basically yeah, um then what you want is like start the sides and then right right right finish is the same thing. I mean.

C

You agree, it seems like there are too many types you dislike a chain of times: yeah God, because I pipe writer could just you basically a log. Then you can keep asking for span and then basically can flash like I also dislike for.

B

C

Is itself today, I think.

B

We wanted smaller surface to pass it down to pass other things, so I sort of things in in theory, this didn't implement an interface like I can write to this thing right and you come out. You guys think Mike. You pass it to a bunch of methods that format into it. Like, for my name for my strength for my blog, you get it back in a unistall flush right, but.

C

What I'm saying is you know what I thought emails asking is basically on the API is that are on the right able buffer beyond beginning, and then we would have you know first less times and second be nice kind of like. Oh, how you know, how far do I have to Train till I actually can do some work. I.

B

Think we wanted like a primitive for buffer chains, kind of on top of that that don't involve the entire writer that you, it.

E

Could be implemented on the actual.

B

Pipe itself, if.

E

We had one, we don't have one yet. So it's a reason, I mean finally missed fewer times. Fear concept. Secondly, I think the like. You need your API. You have to look very carefully, but otherwise it's likely because you could see and say hello, K, the buffer classes around. Look at again. You got a lot of presence around, but that's not what they.

B

D

That's what you.

E

D

Start stop also. We were fighting from this to how my own unique internal occasions. It was for this way. Is there right yeah, because we were not sure thank you supporting it, but I like.

B

The way yeah yeah we could we could we could. uh What do you think would look like just right, parent buffer advance, yeah it'd be exposing the actual span mother's memory on results, basically, like I output, correct this.

C

Is it yeah scream cell, with the flush when I, by the way, we need to add flash to output, I already I.

D

Ran in many cases, I all.

C

Put is like a time that have incur if X were very similar scenarios. We make this cream right here, but with no charge assume that we have play movie.

E

B

Yeah yeah don't raise I'm talking.

B

Okay, that's good feedback, so you there would be a way to allocate a buffer, so you still need a way to allocate about for them. Maybe we call Alex start or are we just call it Alec and it doesn't return its point. Yeah I knew right into the actual.

B

I mean why don't you do like on demand allocation when you're cheap along Department on the span Excel in the denominator, I press cop says you shouldn't do is kind of things indicator.

B

Okay, yeah I, think I mean you kind of want to say like memory if you promoted it and what you're flush kill them, the writer, the pipe writer, is it done when you flush, there's no bail, it's not done complete that so completely I'm done. Writing completely flushes like flush. My current reader that I wrote a thing yeah.

B

You can also make that our kids, if you want to be yeah every.

C

B

B

But console pending so when you call flush flush, returns, unavailable we're leaving my connie Clark's, there's no right, occasionally the buffer. Yes, you know this is where email for.

C

The buffer Cristobal running at the end, basically double use at the end.

B

So this is kind of disaster, but but um so quick trust me explain this one a little bit. Even the diplomats, output, yeah, see ya thing back great and you can get the buffer from it. So you can write to it, but it has it excites. And then you want to grow it. You call insurer or the clincher yeah. So are you growing it? You already allocated a fixed size, but in forever ties its mid-sized record, so you see like gimme 4k and you write to it.

B

You right a lay-oh and you say, like grown a new key phrase over and over and over. So it is to hopping up things like here, so you can build. Higher element is like right and do like so that we want to make yourself done. It should be allocated should be sure should be something close because you're going to change, use. Okay,.

C

B

C

B

C

Yeah, so you know like basically, if you don't call in sure first, you will just return like an empty thing. Yes, which means you don't have to allocate is fast and FX cap doesn't feature up over that yeah.

B

And then there's no like implicit row when you're like yeah yeah.

D

Because it's running so many if.

B

Nobody calls ensures immobilize watching it great, but if you like try to write and you you don't call it sure, because sure that's true anyway, yeah so.

C

Then you see, like all these ideas, would move to I pipe reader. Yes, so nice I mean it. You know like you just go insurer and then you get the buffer yeah yeah. We can pick a person other things.

B

Like you can get, it is that you wrote by calling us ruler yeah what scenarios do you really want that? Oh the other one might want it, but not use super.

B

It's for reasons that out easily so I think people are being to use. This has a scratch buffer, which may not be the intends to let you allocate a buffer, and you just like right to it like give me why I just groped, but that again is kind of using the pool myself. I guess.

C

You don't need.

B

It um I've been period. Make you for now. I'm looking to seep up is nothing wrong. With looking what you waited to wrote there was, there was a kiss for it, regionally that I never seen by camera. What the case was not um it was. It was trying to get a length, so I would see it see. You write a bunch of data and you want to get the length. We just wrote the so-called bytes written and you want to get the contacts you.

D

A

Remove useful things.

D

B

Wrap your life, your writer and you keep track of it yourself, there's so many ways you can't. If so, if you could decorate this thing properly and you like pass through all the data I'll be fine, it's not moving all up the ID pipe writers done interface. You can rub you.

C

B

Decorate this thing, because you explicit buffer- and you can't think you can't wrap it- was returned to someone else that was my wife so hard to look at the data extreme. You you overwrite this buffer already offer is like a hurry. Yeah sure you have a way of reading it. You can't decorate that thing, but you have a way of reading. So you might so imagine you wanted to create this thing. Pasta, but I've read about stuff right that they that they get the controller.

B

Okay and I mean you want to see what the written dad you look at the buffer.

D

Buffer when you overestimate and then you look at the book, it route, 15 chains of buffers- yes or you have there is the last one. But it's early.

B

Or ensure, how do you look at the yeah there's, no way that you know I'm not that create this thing like you in stream, you you afraid right. Do you think you handle on the right color holistically lovers as they pass through? They say that you can do it whenever we call number someone calls come in at bat like what do you do can come up with a scenario why you need to read your first and then we can talk about this. It's like it's like seeing.

B

Wasn't that great, never wait if you can find a reason to decorate stream ran, read commentaries. The those lovers here see my dad right, I feel like we're doubling complexity, we're having a writer a PS to deal all you to region. I'm gonna have a reader.

D

A PSI you're right aren't.

B

C

Right and you can always edit later yeah, if you really think that is there certainly worker as well.

E

As readable, writable buffer make sure it.

B

Is it hats, because this interested.

D

But readable buffer has buffer of buffer, but yes,.

C

Yeah you I understand.

B

For reasons reasons, reasons for reasons: they're bad, but they're good. So what are the reasons if you wanna, if you have this chain of data, this chin of this place? Imagine this is like compression are. This is kind of like pipeline is, and this process in between doing this thing is compression or whatever.

B

You want to take the data from this this pipe and like change in place, and this place it's terrible but later, but oh my god to me the code URLs with no again, you do it list for compression. It doesn't work great because it could always be bigger. Decompression, wait.

A

It's dirty reasons: I, don't think it's bad.

B

Though so, would you be on the result when you when you consume, therefore my pipe yes today? If but the change you guys, wanna propose it to make it read only I'm saying there cases where you wanted to turn that buffer in system, you guys is in four different pipe. They want to write in to see you may want to edit the in place to try to do a transmission with allocating and then pass a lot of different mothers. Yeah.

C

B

Want to be pure to have it be read-only, it prevents us from working all together, but you can ever it has to so I.

C

Almost think that I understand the reason and I think imagine that the terminology was not writable, bother readable by fair reading. Writing, but in putting out and everything is read right and they are just inputs and outputs. That's basically a better terminology given this mother, do you think if a letter will be confusing yeah? It is.

B

Like your audio sorry, but that's why we.

C

C

What you actually mean is pipes are just transports of readwrite byte arrays. Yes, they are not yet for reading or writing. They are just transferred. So I want to read this to my mother and, and the reader and writer just correspond to the ends as to what she's supposed to be doing with this data. This reader.

B

And writer, really less ambiguous and put it out, but like reader and input, seems obvious same and I. Don't know, I didn't thinking the same thing, but don't think I have lesser or dreams, but I do anything. The name your buffer is wrong. They should be but buffer buffer.

D

We also know out return the same if you're doing consumed entire data will give you the same blocks again when you read next time and if you modify them already this, because okay and I think nothing's possible, you get it the first time. You think you have enough him, you modified it, and then you don't have enough. So you, okay, I, don't I, didn't consume anything and they get it next time and it's a little intimidated in.

B

Any problems I, don't feel comfortable removing yet because we only have a single scenario: that's how we use pipes for today, which is like Koechlin sockets. But if we ever do like it seems when you want to modify the buffer in place.

D

B

An API review I think the argument that we should have this API just in case, because we don't we.

C

B

One scenario is kind of a tough argument: it's not nice. Now we have is that we, we actually know a sniper. We perceive wanna.

A

B

B

Run this callback in this location, this is like super low. This is like a if you're gonna implement a primitive for scheduling things, so it would look like, like Java has been called printable. It's basically a this similar fix rate, and you can pass it to arbitrary things. I can schedule callbacks anywhere, but it takes action of what perfect object problem. All it is is write as literally run this function like do a thing with it. So.

C

It's just a delegate: if you want to take parameters or return, you have to get it. The.

B

Thing that accepts it elegantly.

E

C

Corruption, jørgen, which is exactly what I don't you touch it no.

A

You have to and.

C

We should discuss it with Steve yeah I guess. I do owe.

E

You magical action.

C

Unlike on purpose, if we, if we need this time, then it yeah, unless we already have a type that should work for you, yeah, doesn't work basic.

E

B

In care to admit, yeah, I think call a thread pool, but basically the same thing or is like tell me where you want things to run so, for example, in in for our first test, we have a thread, scarcely more dot run in line which which stays on the current transport thread. So you can run single threaded on the Vivi lake in our pipeline. They can just do the single leg scheduler. So you say when you are doing call box for reads, made sure Russ under to be thread kind of works. You have your check.

B

You surely have something.

E

B

Don't have nothing I, don't see anything, nothing at all, nothing good.

C

Even if you know it's not DC I'll say yeah like I, would not put it in this namespace and.

D

I would not all writing is like scheduler.

C

In my schedule, yeah, should it be a abstract class for you Christa? Why would you because then we don't have to have a title in line scheduler, we can have a type called scheduler than TD vault or in line, and you know like it.

E

C

Many problems, performant fermentation.

E

There are many benefits of.

C

B

We can always throw the Aleut some static.

C

I'm ice caps, we discovered it, for example, it's very costly to pass it in through an action of object. We can add an overload that it takes an object action and they need our.

B

Unit I scheduled you.

B

Know I think I think we should agree on these little interface. Like then, I'm you'll agree it'll be sold like minimal and it won't require it. But if it is me in whatever I do I if I service brighter with an abstract base class yeah, that's I. Don't feel that bad about that one. Now it's fine and.

C

You know nobody will ever need more than one megabyte of this. They never did nothing just.

B

Redefine Dominion yeah all right, um one more thing: I want to bring us pretty pretty important. Before we go on I parried, it is a call to advance. This is kind of a fundamental thing that is it different between this stream. So when you call read async you get a result bypass the buffer and that buffer will not move until you call it bats. So this is super important. So let's say the writer wrote like something right, so it looks. Thank you.

B

So the writer is here and the readers here thinking has a cursor or the reader has a cursor to the to the invention of buffers. I was pretty moderator. That's writer! It's used to write data, the readers consuming it pulling the writer like until it go that way right when the reader gets upper back. Let's say it called read: it got this data back right.

B

The reader has to call a device to move the cursor to move this cursor to whatever a consumed right if it doesn't, and you close and keep going to read to get the same data over and over, which means like yeah there's this. You might have to really say, like read: async get some data cloud lines right, so that's kind of disadvantage, as it reads um so we thought about out of advancing was young API, because we want the opportunity dock to advance. I say we hit some kind of separator we're parsing.

B

We want to be able to advance to that separator, not copy out the stuff. We wanna parts next and basically restart the loop just another call every day, sick, so I think that a.

C

Vigor I agree, I understand white. The scenario exists. What I still don't feel super confident is that you have two cursors one char sees in the camera, so I was shooting useful simplifies for just did I consume or not. Yes,.

B

You want to wait so you know what I will take about thread if you have seen everything but haven't consumed everything right. So that's the way to tell us that hey I saw this data. It's only like half the data I don't want to copy it, because that's all.

C

We're trying so would and.

B

I, don't want to be blocking a thread, yes, I would say. If you call it read, you've seen the.

C

Day, no, why not? When would you color it and not see the data, because you want.

B

To live, there are two nice components: right yeah, you have like multiple like methods and they each call read a sink or whatever, and they arts different like sessions. This.

E

Is the basic thinking ahead.

B

You want to do like super CliffsNotes on back pressure like yeah, so one of you that at bass does is there's this there's this chain between this. Is this pull between research, consumer right, I'm, gonna producer? When, when you want to be a situation where you don't overlook the consumer, either way, that's gonna back off. So let's say you create the pipe that's Isley tannery when I write my top may consume. When you get past the threshold of this, this ounce bumper advise kind of relieves the Barbara from the actual producer.

B

So when you sat about and you mark it as consumed, you're relieving this number to be like whatever it is, they're so clear until you hit that specified buffer size when you create the pipe flush, a sink always return to complete the task. It's only once that buffer has been filled up, that flush, async returns an incomplete tasks which completes once the reader has consumed enough of the buffer that there's basically drew, and that happens when you pod that see.

B

You seems nice when you call back that that asks that that act will free up Oni every place. You consume based on what you packed in as a cursor, so another question.

C

That good default be I've, seen the data and you have a separate API that can say like I unsee it, because I want to intern.

D

C

Because I think it's just.

D

Interesting like for.

C

People to call the prism or get the buffer and oh yeah. Yes,.

B

Constant this be considered not seen. You have a separate piece: I rather rename read sages VP that made a default consume everything, because, because cuz everything means returns, it butterfl advanced is looking at as a snippet says, return to the pool and deck when the ref color it for me and and that actually high draft coming from Ling consumers do not see how, because no no no.

C

Travel with, like you know, indicating when I consume beta. What I have a problem with atleast two parameters? One is I, consume the daytime, the otherwise there's.

D

C

Yeah that just takes it, you know, but it's because you look at the API and you cannot understand what the heck is. This thingy right, how can I not see data I just.

B

Read it by no wondering interface when there's a way to just have an Oakland that does the default behavior for like the most kid, the most obvious case, I mean it really. Yes,.

C

Because we don't see the parameter names, advance takes two cursors and one is basically says how much they'd I have seen and how much they'd I have read and I. Think that examined is so weird I named it. The neighborhood would have to.

B

Know what the past there you do the moment you look at the moment. You have written code that Lake is parsing. Some protocol, like this all it was kind of jealous I- need to use this API you're gonna want to see an example or tutorial or a sample. First yeah.

C

Yes, it is I, don't know what I'm saying, but it's such an advanced scenario to basically say I haven't seen it that I would what I would do is by default. You just call advanced and when you consume, it's assumed to be seen when you read and let's can basically call another API. That's like right, yeah they're, just going on over yeah that works.

B

It at do processing using interface law, but there's a thing called like at the.

D

C

That, literally.

B

Takes one and it passes Stanford, but it has two games, because this is the lowest-level League. If we take it from here, we won't have yeah, but I agree like in the most common case. You call it advances one buffer, I.

E

Think it would help also is if we have samples that are actually ballistic I, think your samples are all too complicated yeah about too many concepts yeah any computer samples underneath I think what we really help is like having dedicated sample that literally stationery. My advice puts in 10 bytes and doesn't use are impossible.

C

I'm, sorry I, don't care for refactoring like you can right-click on a bar and say like just or on the whole file in markets with the end part that'll.

E

Be the worst thing you can ever do.

E

Actually, the role you can just control, though that bar and then J changing all you can actually know, and then all false reels of project would ever use that, though, that's a question. I do the other way around by the way right, because you never.

B

Use IDE that, like show me that pipe should.

C

Be me want to be reading something 31, something to request for github. There should be like a HTML. After what are they called like.

E

Ants yeah teachers in the website are not replacing so bad. There are good coding conventions with the.

C

Island first was what about your API, so po8 mom. This is like use our because.

B

We don't see some local variables inside in every single, so.

E

But but the examples would be helpful, yep and then like really really streamlined samples it will. They show the mechanics but I see me go through like most of the core.

B

Types like II mean I explained was I. Don't think that matters that matters it.

C

Was another too.

B

C

Yeah and also we didn't talk about the waiters yeah.

D

C

B

So everyone agrees the name change late.

C

B

Like people not really, since we already named pipes yep, let's call it uh this whole naming it no.

E

Justice, or so you want to remove this faster rather than all right. What is it when I review this faster rather than yes, so another two hours lot this week whole to be good good Perez's. For a day, you were come home on Thursday, Sibley, Wednesday, tomorrow way to say anybody is going on Thursdays, you know, will set it off for Thursday's and then you can sample size.

C

E

Okay, I wanna have lunch. I had online Aware's.
