extend trait for Service providing combinator functionalities.

Provided Methods

fn enclosed<T>(self, build: T) -> Pipeline<Self, T, BuildEnclosed>

where T: Service<Result<Self::Response, Self::Error>>, Self: Sized,

Enclose Self with given T as Service<<Self as Service<_>>::Response>>. In other word T would take Self’s Service::Response type as it’s generic argument of Service<_> impl.

fn enclosed_fn<T, Req>(self, func: T) -> Pipeline<Self, T, BuildEnclosedFn>

where T: for<'s> AsyncClosure<(&'s Self::Response, Req)> + Clone, Self: Sized,

Function version of Self::enclosed method.

fn map<F, Res, ResMap>(self, mapper: F) -> Pipeline<Self, F, BuildMap>

where F: Fn(Res) -> ResMap + Clone, Self: Sized,

Mutate <<Self::Response as Service<Req>>::Future as Future>::Output type with given closure.

fn map_err<F, Err, ErrMap>(self, err: F) -> Pipeline<Self, F, BuildMapErr>

where F: Fn(Err) -> ErrMap + Clone, Self: Sized,

Mutate <Self::Response as Service<Req>>::Error type with given closure.

fn and_then<F>(self, factory: F) -> Pipeline<Self, F, BuildAndThen>

where F: Service<Arg>, Self: Sized,

Chain another service factory who’s service takes Self’s Service::Response output as Service::Request.
