Rust Cologne

Rust Cologne is a monthly meetup dealing with everything Rust.
In March we will have a closer look at abstractions in Rust. How they work, how efficient they are, and how well they live up to the promise of being zero cost.

(The meetup will likely be held in German but we'll switch to English if needed.)

Dear Rustacean,

you are hereby warmly invited to join the next Rust Cologne meetup. Whether you want to speed up your python code, write a web service, need interop with your C++-codebase, cross-compile for a microcontroller, write an emulator, … we've got you covered!

We commonly open up with a brief summary of noteworthy changes in the Rust ecosystem. Be it updates to the language itself, public events, its impact on other projects and languages, …

Rust features various abstractions, some of them promising to be zero cost. Starting from simple things like for-loops. Everything is an iterator, C-style for-loops don't exist.
We will take a look at various abstractions and what code they generate in the end. This will give us an idea of how zero cost they truly are, and how powerful the compiler truly is.

Starting from the implementation of formatting macros we will make our way through the various stages of compilation right down to the assembly.
Each stage will be explained to gain at least a basic understanding of the syntax and operations involved.

As usual, the remaining time is about whatever you want to talk about!

Always wanted to know why Rust is harder to learn than other popular languages or why it lacks a certain feature? When is it appropriate to rewrite a project in Rust? Is the compiler really that slow and are the binaries really that big? Do all those safety guarantees have an impact on the performance? Fetch a drink and let's find out.

See you soon!

Yours,
Florian and Kai
