Rust

Let's setup Emacs for Rust development, shall we ?

rust-mode

rust-mode (in MELPA) offers:

• syntax highlighted,
• code formatting, optionally automatic,
• Imenu support,
• navigation by semantics (go to the beginning or end of the current defun), (see also helm-swoop, helm-ag, tags,…)
• playpen helpers (send the selected code to play.rust-lang.org),
• …

In Debian testing and unstable you can also install it with apt install elpa-rust-mode (but the MELPA way is prefered).

Code formatting with rustfmv

Formatting is also provided by this mode. If you want auto formatting everytime you save a buffer, put this in your Init File:

(setq rust-format-on-save t)

On-the-fly syntax checking: Flycheck-rust

See flycheck-rust (on MELPA). See Flycheck.
