Integration Information

  Since Vim does not detect the rust file type out-of-the-box, you need the
  runtime files for rust from here: https://github.com/rust-lang/rust.vim

  Note that there are two possible linters for rust files:

  1. rustc -- The Rust compiler is used to check the currently edited file.
     So, if your project consists of multiple files, you will get some errors
     when you use e.g. a struct which is defined in another file. You can use
     |g:ale_rust_ignore_error_codes| to ignore some of these errors.
  2. cargo -- If your project is managed by Cargo, the whole project is
     checked. That means that all errors are properly shown, but cargo can
     only operate on the files written on disk, so errors will not be reported
     while you type.

  Only cargo is enabled by default. To switch to using rustc instead of cargo,
  configure |g:ale_linters| appropriately: >

  " See the help text for the option for more information.
  let g:ale_linters = {'rust': ['rustc']}
<

  Also note that rustc 1.12. or later is needed.

cargo                                                          *ale-rust-cargo*

g:ale_rust_cargo_use_check                         *g:ale_rust_cargo_use_check*
                                                   *b:ale_rust_cargo_use_check*
  Type: |Number|
  Default: `0`

  When set to `1`, this option will cause ALE to use "cargo check" instead of
  "cargo build". "cargo check" is supported since version 1.16.0 of Rust.

g:ale_rust_ignore_error_codes                   *g:ale_rust_ignore_error_codes*
                                                *b:ale_rust_ignore_error_codes*
  Type: |List| of |String|s
  Default: []

  This variable can contain error codes which will be ignored. For example, to
  ignore most errors regarding failed imports, put this in your .vimrc
  >
  let g:ale_rust_ignore_error_codes = ['E0432', 'E0433']
