Welcome to the Standard Library Development Guide! This book is for anybody who is contributing to, or who is reviewing contributions to, the standard library. It aims to capture everything you need to know through the whole lifecycle of a standard library feature, from inception through to an initial unstable implementation, through to stabilization, and eventually maybe deprecation.
The latest version of this guide is available on https://std-dev-guide.rust-lang.org/
The guide is a very early work in progress. It still has big gaps. If there's a section you'd like to flesh out, please feel free to submit a PR or raise an issue!
- The Rustc Dev Guide: A similar resource for the Rust compiler itself.
- The Libs Team Repository: The home of the Library Team, who maintain this book.
