Servers Rust

Rust Language Server (aka RLS)

RLS is in the alpha stage of development. It may not work as expected in some cases.

Installing server

rustup update
rustup component add rls-preview rust-analysis rust-src

Follow instructions at https://github.com/rust-lang-nursery/rls#setup in order to install and setup rust language server.

Registering in .vimrc

This code requires neovim v0.2.0+; in earlier versions, it will cause a syntax error.

if executable('rls')
    au User lsp_setup call lsp#register_server({
        \ 'name': 'rls',
        \ 'cmd': {server_info->['rustup', 'run', 'nightly', 'rls']},
        \ 'root_uri':{server_info->lsp#utils#path_to_uri(lsp#utils#find_nearest_parent_file_directory(lsp#utils#get_buffer_path(), 'Cargo.toml'))},
        \ 'whitelist': ['rust'],
        \ })
