* Description
This layer aims to support [[http://www.rust-lang.org/][Rust]] development in Spacemacs.

It supports [[http://doc.crates.io/index.html][Cargo]], and has some basic auto-completion support through [[https://github.com/phildawes/racer][Racer]],
though Racer needs some additional configurations as described on their page.

* Install
** Layer
To use this layer, add it to your =~/.spacemacs=

#+BEGIN_SRC emacs-lisp
(setq-default dotspacemacs-configuration-layers '(rust))
#+END_SRC

** Cargo
[[http://doc.crates.io/index.html][Cargo]] is a project management command line tool for Rust. Installation
instructions can be found on the main page of [[http://doc.crates.io/index.html][Cargo]].

** Auto-completion
To enable auto-completion, ensure that the =auto-completion= layer is enabled and
add the following line to your =dotspacemacs/user-init=:

#+BEGIN_SRC emacs-lisp
(setq-default rust-enable-racer t)
#+END_SRC

You have to install [[https://github.com/phildawes/racer][Racer]] to use this. For more information on the installation
procedure, look [[https://github.com/racer-rust/emacs-racer][here]].
