This repository collects resources for writing clean, idiomatic Rust code. Please bring your own. :blush:
> *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](https://github.com/tim-hr/stuff/wiki/Idiomatic-coding)

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 this amazing article about spellchecker for example: http://norvig.com/spell-correct.html.
