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.
