![Logo](idiomatic-rust.png) ![Build Status - Check Links](https://github.com/mre/idiomatic-rust/workflows/Check%20Links/badge.svg) This repository collects resources for writing clean, idiomatic Rust code. [Please bring your own.](https://github.com/mre/idiomatic-rust/blob/master/CONTRIBUTING.md) :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) ## ⚙ Projects * [Rust Anthology](https://github.com/brson/rust-anthology) - The best short-form writing about Rust, collected. * [cheat.rs - Idiomatic Rust tips](https://cheats.rs/#idiomatic-rust) - A list of quick tips to make your code more idiomatic. * [clippy](https://github.com/Manishearth/rust-clippy) - A bunch of lints to catch common mistakes and improve your Rust code. * [Patterns](https://github.com/rust-unofficial/patterns) - A catalogue of Rust design patterns. * [Elements of Rust](https://github.com/ferrous-systems/elements-of-rust) - A collection of software engineering techniques for effectively expressing intent with Rust. * [Rust by Example](https://rustbyexample.com/) - A community driven collection of example code which follow Rust best practices. * [Rust Cookbook](https://github.com/brson/rust-cookbook) - Examples that demonstrate good practices to accomplish common programming tasks in Rust. * [rust-api-guidelines](https://github.com/brson/rust-api-guidelines) - An extensive list of recommendations for idiomatic Rust APIs. ## 🏋 Workshops * [Build your own JIRA with Rust](https://github.com/LukeMathWalker/build-your-own-jira-with-rust/) - A test-driven workshop to learn Rust building your own JIRA clone! * [Ferrous Systems Teaching Material](https://ferrous-systems.github.io/teaching-material/index.html) - Free workshop material produced by Ferrous Systems for trainings.

Functional, imperative or a mix?](https://users.rust-lang.org/t/which-is-more-idiomatic-functional-imperative-or-a-mix/11278) * [An idiomatic way to sum up values in a multidimensional Array](https://users.rust-lang.org/t/an-idiomatic-way-to-sum-up-values-in-a-multidimensional-array/9485) ## 📜 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](https://norvig.com/spell-correct.html) and [sudoku solvers](https://norvig.com/sudoku.html). And, of course, the [Zen of Python](https://www.python.org/dev/peps/pep-0020/). 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 ;-) ## 🔏 License [![CC0](https://i.creativecommons.org/p/zero/1.0/88x31.png)](https://creativecommons.org/publicdomain/zero/1.0/) To the extent possible under law, [Matthias Endler](https://endler.dev) has waived all copyright and related or neighboring rights to this work.
