Spawn a new language server process and start the background reader thread.

pub fn initialize( &mut self, workspace_root: &Path, initialization_options: Option<Value>, ) -> Result<InitializeResult, LspError>

Send the initialize request and wait for response. Transition to Ready.

pub fn diagnostic_capabilities(&self) -> Option<&ServerDiagnosticCapabilities>

pub fn supports_watched_files(&self) -> bool

Whether the server supports workspace/didChangeWatchedFiles. Captured from the initialize response. Default false (conservative).

pub fn send_request<R>( &mut self, params: R::Params, ) -> Result<R::Result, LspError>

where R: Request, R::Params: Serialize, R::Result: DeserializeOwned,

Send a request and wait for the response.

pub fn send_notification<N>( &mut self, params: N::Params, ) -> Result<(), LspError>

where N: Notification, N::Params: Serialize,

Send a notification (fire-and-forget).

pub fn shutdown(&mut self) -> Result<(), LspError>

Graceful shutdown: send shutdown request, then exit notification.

pub fn state(&self) -> ServerState
