# rust-analyzer

rust-analyzer is a language server that provides IDE functionality for writing Rust programs. You can use it with any editor that supports the Language Server Protocol (VS Code, Vim, Emacs, Zed, etc).

rust-analyzer features include go-to-definition, find-all-references, refactorings and code completion. rust-analyzer also supports integrated formatting (with rustfmt) and integrated diagnostics (with rustc and clippy).

Internally, rust-analyzer is structured as a set of libraries for analyzing Rust code. See Architecture for more details.

The manual is written in markdown and includes some extra files which are generated from the source code. Run `cargo test` and `cargo xtask codegen` to create these.

If you have questions about using rust-analyzer, please ask them in the “IDEs and Editors” topic of Rust users forum.
