pub trait ServerStreamingService<R>:
    Send
    + Sync
    + 'static {
    type Response;
    type ResponseStream: Stream<Item = Result<Self::Response, Status>>;

    // Required method
    fn serve(
        &self,
        request: Request<R>,
    ) -> impl Future<Output = Result<Response<Self::ResponseStream>, Status>>;
}

Available on crate features http and grpc only.

A specialization of Service.

Existing Service implementations with the correct form will automatically implement ServerStreamingService.

Required Associated Types

type Response

Protobuf response message type

type ResponseStream: Stream<Item = Result<Self::Response, Status>>

Implementors

impl<T, S, M1, M2> ServerStreamingService<M1> for T

where T: Service<Request<M1>, Output = Response<S>, Error = Status>, S: Stream<Item = Result<M2, Status>>,

type Response = M2

type ResponseStream = S
