--- See [docs](https://rust-analyzer.github.io/book/configuration.html) for extra settings. The settings can be used like this:
|

--- ```lua
|
||||
--- vim.lsp.config('rust_analyzer', {
|
||||
--- settings = {
|
||||
--- ['rust-analyzer'] = {
|

--- diagnostics = {

--- enable = false;
|
||||
--- }
|
||||
--- }
|
||||
--- }
|
||||
--- })
|
||||
--- ```
|
||||
---
|
||||
--- Note: do not set `init_options` for this LS config, it will be automatically populated by the contents of settings["rust-analyzer"] per
