Rust in October: Macro-magic

Rust Cologne is a monthly meetup dealing with everything Rust.
In this meetup we'll talk about how to alter the language's capabilities using various macro techniques.

(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, …

In this meetup we'll talk about Rust macros. Macros are a measure to simplify repetitive code, remove boilerplate, create DSLs (domain specific languages) or get around language limitations. There are multiple flavors available and each has their own up- and downsides. We'll show how to use these methods by creating an examples, see how the compiler builds and runs procedural macros and how the rust-analyzer can assist when developing with macros.

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
