flycheck-rust — Flycheck for Rust

Build Status License GPL 3 MELPA

This Flycheck extension configures Flycheck automatically for the current Cargo project.


Install from MELPA or MELPA Stable.

If you use Cask:

(source gnu)
(source melpa)

(depends-on "flycheck-rust")

Then, in your init.el:

(with-eval-after-load 'rust-mode
  (add-hook 'flycheck-mode-hook #'flycheck-rust-setup))


Just use Flycheck as usual in your Rust/Cargo projects. flycheck-rust-setup will call cargo to determine your project layout and set the variables needed by the rust-cargo checker to properly check your buffer.

You may also want to have a look at flycheck/flycheck-inline, which works well with diagnostics emitted by Rust.
