Definition of the gRPC trait alias for tower_service.

This trait enforces that all tower services provided to Grpc implements the correct traits.

Associated Types

type ResponseBody: Body

Responses body given by the service.

type Error: Into<Box<dyn Error + Send + Sync>>

Errors produced by the service.

type Future: Future<Output = Result<Response<Self::ResponseBody>, Self::Error>>

The future response value.

Required methods

fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Ready when the service is able to process requests.

Reference Service::poll_ready.

fn call(&mut self, request: Request<ReqBody>) -> Self::Future

Process the request and return the response asynchronously.

Reference Service::call.
