rust-analyzer is a Language Server Protocol implementation providing IDE features for Rust, including code completion, go-to-definition, find references, refactorings, and integrated diagnostics. It works with any LSP-capable editor such as VS Code, Vim, Emacs, and Zed, and is internally structured as a set of libraries for analyzing Rust code.

Use cases

• get IDE features for Rust in Vim or Emacs
• go to definition and find all references in Rust code
• autocomplete Rust code in my editor
• run rustfmt and clippy diagnostics inside my editor
• refactor Rust code with rename and code actions
• set up a language server for Rust development

When to choose

• you write Rust and want IDE features in any LSP-compatible editor
• you need code intelligence (completion, navigation, refactoring) for Rust codebases
• you want integrated rustfmt formatting and rustc/clippy diagnostics in your editor

When to avoid

• you need IDE support for languages other than Rust
• you want a full standalone IDE rather than an editor plugin/language server
• you need a Rust compiler backend or code execution tooling rather than static analysis
