Add support for Rust using rustc and cargo (#230) * Add rustc checker for rust files * Add documentation for rustc * Use a nice helper function * Add cargo as linter * Complete the doc for rust linters * Put l: in front of every local variable * Apply the requested stylistic changes 2017-01-12 09:33:55 +00:00			`" Author: Daniel Schemala <istjanichtzufassen@gmail.com>`

Make cargo linter lighter: (#408) - Use `cargo check` instead of `cargo build` when `g:ale_rust_cargo_use_check` is truish. - Use `--frozen` to avoid locking the project. 2017-03-27 11:37:00 +00:00			`let g:ale_rust_cargo_use_check = get(g:, 'ale_rust_cargo_use_check', 0)`

Add a script for custom checks to enforce using the abort flag for functions and trailing whitespace, and fix existing issues. 2017-01-22 14:54:57 +00:00			`function! ale_linters#rust#cargo#GetCargoExecutable(bufnr) abort`
