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
