Rust

Install

The LSP server for rust is rls.

On Debian Testing the toolchain returns stable-x86_64-unknown-linux-gnu.

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
rustup component add rls rust-analysis rust-src --toolchain stable-x86_64-unknown-linux-gnu

IMPORTANT: make sure rls runs after install

Neovim

Plugins

Plugins managed by vim-plug

The LSP client used is ale.

NOTE: ale works only inside a cargo generated project (i.e. it will search for Cargo.toml)

Plug 'dense-analysis/ale'
Plug 'rust-lang/rust.vim'

Configuration

This will set various fixers including rustfmt and rls as the linter.

let g:rustfmt_autosave = 1
let g:ale_fixers = {
\   '*': ['remove_trailing_lines', 'trim_whitespace'],
\   'rust': ['rustfmt'],
\}
let g:ale_linters = { 'rust': ['rls'], }
