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 three 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.
  3. rls -- If you have `rls` installed, you might prefer using this linter
     over cargo. rls implements the Language Server Protocol for incremental
     compilation of Rust code, and can check Rust files while you type. `rls`
     requires Rust files to contained in Cargo projects.
  4. rustfmt -- If you have `rustfmt` installed, you can use it as a fixer to
     consistently reformat your Rust code.

  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: `1`

  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.

  ALE will never use `cargo check` when the version of `cargo` is less than
  0.17.0.


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

  When set to `1`, ALE will set the `--all-targets` option when `cargo check`
  is used. See |g:ale_rust_cargo_use_check|,


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

  When set to `1`, ALE will set the `--tests` option when `cargo check`
  is used. This allows for linting of tests which are normally excluded.
  See |g:ale_rust_cargo_use_check|,


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

  When set to `1`, ALE will set the `--examples` option when `cargo check`
  is used. This allows for linting of examples which are normally excluded.
  See |g:ale_rust_cargo_use_check|,


g:ale_rust_cargo_default_feature_behavior
                                    *g:ale_rust_cargo_default_feature_behavior*
                                    *b:ale_rust_cargo_default_feature_behavior*
  Type: |String|
  Default: `default`

  When set to `none`, ALE will set the `--no-default-features` option when
  invoking `cargo`. Only the features specified in
  |g:ale_rust_cargo_include_features| will be included when performing the
  lint check.

  When set to `default`, ALE will instruct `cargo` to build all default
  features specified in the project's `Cargo.toml` file, in addition to
  including any additional features defined in
  |g:ale_rust_cargo_include_features|.

  When set to `all`, ALE will set the `--all-features` option when
  invoking `cargo`, which will include all features defined in the project's
  `Cargo.toml` file when performing the lint check.


g:ale_rust_cargo_include_features           *g:ale_rust_cargo_include_features*
                                            *b:ale_rust_cargo_include_features*
  Type: |String|
  Default: `''`

  When defined, ALE will set the `--features` option when invoking `cargo` to
  perform the lint check. See |g:ale_rust_cargo_default_feature_behavior|.

g:ale_rust_cargo_avoid_whole_workspace *g:ale_rust_cargo_avoid_whole_workspace*
                                       *b:ale_rust_cargo_avoid_whole_workspace*
  Type: |Number|
  Default: `1`

  When set to 1, and ALE is used to edit a crate that is part of a Cargo
  workspace, avoid building the entire entire workspace by invoking
  `cargo` directly in the crate's directory. Otherwise, behave as usual.


===============================================================================
rls                                                              *ale-rust-rls*

g:ale_rust_rls_executable                           *g:ale_rust_rls_executable*
                                                    *b:ale_rust_rls_executable*
  Type: |String|
  Default: `'rls'`

  This variable can be modified to change the executable path for `rls`.


g:ale_rust_rls_toolchain                             *g:ale_rust_rls_toolchain*
                                                     *b:ale_rust_rls_toolchain*
  Type: |String|
  Default: `'nightly'`

  This option can be set to change the toolchain used for `rls`. Possible
  values include `'nightly'`, `'beta'`, and `'stable'`.

  The `rls` server will only be started once per executable.


===============================================================================
rustc                                                          *ale-rust-rustc*


g:ale_rust_rustc_options                             *g:ale_rust_rustc_options*
                                                     *b:ale_rust_rustc_options*
  Type: |String|
  Default: `'-Z no-trans'`

  The variable can be used to change the options passed to `rustc`.

  `-Z no-trans` should only work with nightly builds of Rust. Be careful when
  setting the options, as running `rustc` could execute code or generate
  binary files.


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']


===============================================================================
rustfmt                                                      *ale-rust-rustfmt*

g:ale_rust_rustfmt_options                         *g:ale_rust_rustfmt_options*
                                                   *b:ale_rust_rustfmt_options*
  Type: |String|
  Default: `''`

  This variable can be set to pass additional options to the rustfmt fixer.
