Servers Rust

Rust Analyzer

rust-analyzer replaces RLS, which is now deprecated.

Installing server

rustup update
rustup component add rust-analyzer

Registering in .vimrc

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

if executable('rustup')
    au User lsp_setup call lsp#register_server({
        \ 'name': 'rust-analyzer',
        \ 'cmd': {server_info->['rustup', 'run', 'stable', 'rust-analyzer']},
        \ 'allowlist': ['rust'],
        \ })
endif
