The official Rust Compiler Development Guide, an mdBook-based documentation project explaining how rustc works internally. It helps new contributors get oriented to the compiler codebase and serves as a reference for experienced developers.

Use cases

• learn how the rustc compiler works internally
• contribute to the Rust compiler
• understand rustc's bootstrapping and build process
• find where to start with beginner compiler issues
• understand rustc's compilation pipeline from source to binaries
• debug and profile the Rust compiler

When to choose

• you want to contribute to rustc development
• you need to understand compiler internals like type checking, borrow checking, or MIR
• you are onboarding onto the Rust compiler codebase
• you want authoritative, community-maintained rustc documentation

When to avoid

• you need documentation for the Rust language itself or the standard library
• you want a tutorial on programming in Rust
• you need stable, versioned API docs rather than a living guide
