An extension trait for Services that provides a variety of convenient adapters

Provided methods

Important traits for Ready<'a, T, Request>

impl<'a, T, Request> Future for Ready<'a, T, Request> where
    T: Service<Request>,  type Output = Result<(), T::Error>;

fn ready(&mut self) -> Ready<Self, Request> where
    Self: Sized, 

A future yielding the service when it is ready to accept a request.

Important traits for Oneshot<S, Req>

impl<S, Req> Future for Oneshot<S, Req> where
    S: Service<Req>,  type Output = Result<S::Response, S::Error>;

fn oneshot(self, req: Request) -> Oneshot<Self, Request> where
    Self: Sized, 

Consume this Service, calling with the providing request once it is ready.

fn call_all<S>(self, reqs: S) -> CallAll<Self, S> where
    Self: Sized,
    Self::Error: Into<Error>,
    S: Stream<Item = Request>, 

Process all requests from the given Stream, and produce a Stream of their responses.

This is essentially Stream<Item = Request> + Self => Stream<Item = Response>. See the documentation for CallAll for details.
