Struct tower_lsp::LspService

pub struct LspService { /* fields omitted */ }

Service abstraction for the Language Server Protocol.

This service takes a JSON-RPC request as input and produces a JSON-RPC response as output. If the incoming request is a notification, then the corresponding response string will be empty.

This implements tower_service::Service in order to remain independent from the underlying transport and to facilitate further abstraction with middleware.

Methods

impl LspService

pub fn new<T>(server: T) -> (Self, MessageStream) where
    T: LanguageServer, 

Creates a new LspService with the given server backend, also returning a stream of notifications from the server back to the client.

pub fn with_handler<T, U>(server: T, handler: U) -> (Self, MessageStream) where
    T: LanguageServer,
    U: Into<IoHandler>, 

Creates a new LspService with the given server backend a custom IoHandler.

Important traits for ExitReceiver

impl Future for ExitReceiver type Output = Result<(), Canceled>;

pub fn close_handle(&self) -> ExitReceiver

Returns a close handle which signals when the exit notification has been received.
