Rust in August: Don't panic! …or_else?

Rust Cologne is a monthly meetup dealing with everything Rust.
This time we'll talk about error handling, panics, Results and the `?`-operator.

(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, …

This time we'll have a look at different approaches on how to handle errors. What kinds of errors exist, and how to handle them. When is it ok to panic? How to make sure that no error gets unnoticed? We'll also talk about pitfalls when using Results for Threads or async tasks and the current state of the question mark operator.

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
