Trait Implementations

impl<T, F, In, Out, Request> NewService<In> for ApplyNewService<T, F, In, Out, Request> where     T: NewService<Request>,     F: Fn(In, &mut T::Service) -> Out + Clone,     Out: IntoFuture,     Out::Error: From<T::Error>,

type Response = Out::Item

Responses given by the service

type Error = Out::Error

Errors produced by the service

type Service = Apply<T::Service, F, In, Out, Request>

The Service value created by this factory

type InitError = T::InitError

Errors produced while building a service.

type Future = ApplyNewServiceFuture<T, F, In, Out, Request>

The future of the Service instance.

fn new_service(&self) -> Self::Future

Create and return a new service value asynchronously.

fn apply<T, I, F, Out, Req>(     self,     service: I,     f: F ) -> AndThenNewService<Self, ApplyNewService<T, F, Self::Response, Out, Req>> where     Self: Sized,     T: NewService<Req, InitError = Self::InitError, Error = Self::Error>,     I: IntoNewService<T, Req>,     F: Fn(Self::Response, &mut T::Service) -> Out + Clone,     Out: IntoFuture<Error = Self::Error>,

Apply function to specified service and use it as a next service in chain.

fn and_then<F, B>(self, new_service: F) -> AndThenNewService<Self, B> where     Self: Sized,     F: IntoNewService<B, Self::Response>,     B: NewService<Self::Response, Error = Self::Error, InitError = Self::InitError>,

Call another service after call to this one has resolved successfully.

fn from_err<E>(self) -> FromErrNewService<Self, E> where     Self: Sized,     E: From<Self::Error>,

NewService that create service to map this service's error and new service's init error to any error implementing From for this servicesError`.

fn then<F, B>(self, new_service: F) -> ThenNewService<Self, B> where     Self: Sized,     F: IntoNewService<B, Result<Self::Response, Self::Error>>,     B: NewService<Result<Self::Response, Self::Error>, Error = Self::Error, InitError = Self::InitError>,

Create NewService to chain on a computation for when a call to the service finished, passing the result of the call to the next service B.

fn map<F, R>(self, f: F) -> MapNewService<Self, F, R> where     Self: Sized,     F: Fn(Self::Response) -> R,

Map this service's output to a different type, returning a new service of the resulting type.

fn map_err<F, E>(self, f: F) -> MapErrNewService<Self, F, E> where     Self: Sized,     F: Fn(Self::Error) -> E,

Map this service's error to a different error, returning a new service.

fn map_init_err<F, E>(self, f: F) -> MapInitErr<Self, F, E> where     Self: Sized,     F: Fn(Self::InitError) -> E,

Map this service's init error to a different error, returning a new service.

impl<T, F, In, Out, Request> Clone for ApplyNewService<T, F, In, Out, Request> where     T: NewService<Request> + Clone,     F: Fn(In, &mut T::Service) -> Out + Clone,     Out: IntoFuture,

fn clone(&self) -> Self

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
