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, O>( self, func: T, ) -> Pipeline<Self, AsyncFn<T>, BuildEnclosed>

where T: AsyncFn(&Self::Response, Req) -> O + Clone, Self: Sized,

Function version of Self::enclosed method.

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

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, MapErr<F>, BuildEnclosed>

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.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
