Struct tower_lsp::LspService

pub struct LspService { /* fields omitted */ }

Service abstraction for the Language Server Protocol.

This service takes an incoming JSON-RPC message as input and produces an outgoing message as output. If the incoming message is a server notification or a client response, then the corresponding response will be None.

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

Pending requests can be canceled by issuing a $/cancelRequest notification.

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

Implementations

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