Emacs

Rust-mode provides core workflow support. rustic

Rust-mode

rust-mode makes editing Rust code with Emacs enjoyable. It requires Emacs 25 or later, and is included in both Emacs Prelude and Spacemacs by default.

rust-mode provides:

• Syntax highlighting (for Font Lock Mode)
• Indentation
• Integration with Cargo, clippy and rustfmt

This mode does not provide auto completion, or jumping to function / trait definitions.

rustic mode

Rustic is based on rust-mode and provides additional features:

• cargo popup
• multiline error parsing
• translation of ANSI control sequences through xterm-color
• async org babel
• automatic LSP configuration with eglot or lsp-mode
• [eask][] for testing

rustic only shares the rust-mode code from rust-mode.el and rust-utils.el.
