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.

The service shuts down and stops serving requests after the exit notification is received.

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.

    U: Into<IoHandler>, 

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