rust-mode is an Emacs major mode providing syntax highlighting, indentation, and integration with Cargo, clippy, and rustfmt for editing Rust code. It is lightweight and intentionally excludes features like auto-completion and LSP, which are left to companion packages.
Use cases
- edit Rust files in Emacs with syntax highlighting
- get proper Rust indentation in Emacs
- run cargo and clippy from Emacs
- format Rust code with rustfmt inside Emacs
- insert dbg! macros quickly while debugging Rust
When to choose
- you use Emacs and want a lightweight, official Rust editing mode
- you want basic Rust support without a heavy IDE-like setup
- you pair it with eglot or lsp-mode for LSP features
When to avoid
- you want an all-in-one Rust IDE experience in Emacs (consider rustic)
- you use a different editor like VS Code or Neovim
- you need auto-completion and jump-to-definition out of the box
