Trait Implementations

impl<R, S, MF, RF, T, E, Fut, ReqData> Service<R> for MapFutureWithRequestDataService<S, RF, MF>where S: Service<R>, RF: FnMut(&R) -> ReqData, MF: FnMut(ReqData, S::Future) -> Fut, E: From<S::Error>, Fut: Future<Output = Result<T, E>>,

type Response = T

Responses given by the service.

type Error = E
