Rust Programming Language / Rust Cologne

Rust promisses Zero-Cost Abstractions.
In this talk we’ll look at ways to analyze generated code to determine their actual overhead.

hot-upgradable runtime in substrate thanks to Rust

2018 is the year of WebAssembly.
But did you know, you can do more than “Web” with it?
In this talk we’ll investigate how wasm allows substrate,
the Rust blockchain framework that will run Polkadot,
to provide a hot-upgradable, fully configurable
blockchain runtime that runs at native speed (most of the time).

I’ll take some time to explain what is Wayland and why it’s here to stay.
Then, I’ll give a high level overview of the state of Rust on Wayland:
how to write servers and clients, and how far along we can get with Rust.
I want to focus on Smithay projects, and wlroots-rs.

This talk explains how you can use the Fn* traits to properly accept functions and closures as function parameters,
and gives an overview of which closures implement which traits.

People coming from other languages can find a lot of familiar aspects in Rust’s traits:
Traits are somewhat like interfaces, and also somewhat like type classes, and also like… classes?
This talk will try to give you an overview of what traits are and how you can use them to make your code more concise and flexible.

‘Share Secrets Safely’ scratches a particular itch as it provides the tooling required to use GPG in teams with great user experience, while providing all tooling necessary to introduce said shared secrets into their final destination without them ever touching disk. I will particularly highlight the way the project is structured, and tested, showing that ‘journey’ level testing is now affordable thanks to Rust.



Sebastian Thiel

During a recent Python Hackathon in Düsseldorf, Matthias somehow managed to sneak in some Rust code while writing a fast, safe Python module for encoding and decoding JSON. It passes (most of) the Python test suite for the json module and was unreasonably pleasant to write. Listen carefully as he tells the story of a little side-project that got out of hand and how Rust can help speed up even the most boring, highly-optimized tasks like parsing file formats in the future.



Matthias Endler

One of the great things about Rust is that it gives you a lot of control if you need it. Amongst other things it gives you control over memory. How big is your data structure really, and where should it be allocated. This talk will look at caching in modern CPUs in conjunction with Rust data types and data structures. We will see how efficient code can be written to best utilize the cache.

Rust's support for inline assembly is currently unstable. The talk will give an overview of the current unstable implementation in Rust, as well as inline assembly support available in other programming languages. This will lead into a discussion about a sensible design for this feature and a way to stabilize this eventually.

“I’ll just write a simple API wrapper for that. Give me two hours.” Does that sound oddly familiar? Don’t be fooled: writing an easy to use, idiomatic abstraction layer is a lot of work - in any language. I want to tell you my story about writing a Slack client in Rust. From documentation to testing and error handling there’s a lot of pitfalls to avoid and laughs to share.

Better refuel before we get started, this is a “Choose Your Own Adventure” talk—where the audience decides into which rabbit hole(s) we go down. Writing an actual app? Sure! Type system excursions? Always? Or maybe something about our test shenanigans? And of course fields of generated code as far as the eye can see!
