Walkthrough: a typical contribution There are a lot of ways to contribute to the Rust compiler, including fixing bugs, improving performance, helping design features, providing feedback on existing features, etc. This chapter does not claim...
Implementing new language features When you want to implement a new significant feature in the compiler, you need to go through this process to make sure everything goes smoothly. NOTE: This section is for language features, not library fea...

Stability attributes This section is about the stability attributes and schemes that allow stable APIs to use unstable APIs internally in the rustc standard library. NOTE: this section is for library features, not language features. For ins...
Request for stabilization NOTE: This page is about stabilizing language features. For stabilizing library features, see Stabilizing a library feature. Once an unstable feature has been well-tested with no outstanding concerns, anyone may pu...
Stabilization report template What is this? This is a template for stabilization reports of language features. The questions aim to solicit the details most often needed. These details help reviewers to identify potential problems upfront....
Feature gates This chapter is intended to provide basic help for adding, removing, and modifying feature gates. For how rustc enforces and checks feature gates in the compiler pipeline, see Feature Gate Checking. Note that this is specific...
Coding conventions This chapter covers formatting, coding for correctness, using crates from crates.io, and some tips on structuring your PR for easy review. Formatting and the tidy script rustc is moving towards the Rust standard coding st...
Procedures for breaking changes This page defines the best practices procedure for making bug fixes or soundness corrections in the compiler that can cause existing code to stop compiling. This text is based on RFC 1589. Motivation From tim...
Using external repositories The rust-lang/rust git repository depends on several other repos in the rust-lang organization. There are three main ways we use dependencies: 1. As a Cargo dependency through crates.io (e.g. rustc-rayon) 2. As a...
Fuzzing For the purposes of this guide, fuzzing is any testing methodology that involves compiling a wide variety of programs in an attempt to uncover bugs in rustc. Fuzzing is often used to find internal compiler errors (ICEs). Fuzzing can...
Notification groups The notification groups are an easy way to help out with rustc in a "piece-meal" fashion, without committing to a larger project. Notification groups are easy to join (just submit a PR!) and joining does not entail any p...
