rls

rls, a language server for Rust

See https://github.com/rust-lang/rls#setup to setup rls itself. See https://github.com/rust-lang/rls#configuration for rls-specific settings. All settings listed on the rls configuration section of the readme must be set under settings.rust as follows:

nvim_lsp.rls.setup {
  settings = {
    rust = {
      unstable_features = true,
      build_on_save = false,
      all_features = true,
    },
  },
}

If you want to use rls for a particular build, eg nightly, set cmd as follows:

cmd = {"rustup", "run", "nightly", "rls"}

Setup

require'lspconfig'.rls.setup{}

Default values

cmd = { "rls" }
filetypes = { "rust" }
root_dir = function(startpath)
    return M.search_ancestors(startpath, matcher)
  end
