Trait tonic::server::StreamingService

pub trait StreamingService<R> {
    type Response;
    type ResponseStream: Stream<Item = Result<Self::Response, Status>>;
    type Future: Future<Output = Result<Response<Self::ResponseStream>, Status>>;

    // Required method
    fn call(&mut self, request: Request<Streaming<R>>) -> Self::Future;
}

A specialization of tower_service::Service.

Existing tower_service::Service implementations with the correct form will automatically implement StreamingService.
