-- https://github.com/rust-lang/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:
--
-- ```lua
-- vim.lsp.config('rls', {
--   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:
--
-- ```lua
-- cmd = {"rustup", "run", "nightly", "rls"}
-- ```
return {
  cmd = { 'rls' },
  filetypes = { 'rust' },
  root_markers = { 'Cargo.toml' },
}
