---
--- 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"}
--- ```

---@type vim.lsp.Config
return {
  cmd = { 'rls' },
  filetypes = { 'rust' },
  root_markers = { 'Cargo.toml' },
}
