This repository collects resources for writing clean, idiomatic Rust code. Please bring your own. 😊
Idiomatic coding means following the conventions of a given language. It is the most concise, convenient, and common way of accomplishing a task in that language, rather than forcing it to work in a way the author is familiar with from a different language. - Adapted from Tim Mansfield

📜 History
Coming from Python I loved to have some guidelines on how "idiomatic Python" looks like. I was inspired by the likes of Peter Norvig, who wrote amazing articles on spellcheckers and sudoku solvers. And, of course, the Zen of Python.
The goal of this project is to create a peer-reviewed collection of articles/talks/repos which teach idiomatic Rust style. It's a community project. If this becomes a thing I plan to move it to some "semi-official" place like rust-nursery or so. But first I need YOUR help for that ;-)
