Trait Implementations

impl<T, F, R, In, Out, Err> Clone for Apply<T, F, R, In, Out, Err> where
    T: Service<Error = Err> + Clone,
    F: Fn(In, &T) -> R + Clone,
    R: Future<Output = Result<Out, Err>>, 

pub fn clone(&self) -> Apply<T, F, R, In, Out, Err>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, F, R, In, Out, Err> Service for Apply<T, F, R, In, Out, Err> where
    T: Service<Error = Err>,
    F: Fn(In, &T) -> R,
    R: Future<Output = Result<Out, Err>>, 

type Request = In

Requests handled by the service.

type Response = Out

Responses given by the service.

type Error = Err

Errors produced by the service.

type Future = R

The future response value.

pub fn poll_ready(
    &self,
    cx: &mut Context<'_>
) -> Poll<Result<(), <Apply<T, F, R, In, Out, Err> as Service>::Error>>

Returns Ready when the service is able to process requests.

pub fn poll_shutdown(&self, cx: &mut Context<'_>, is_error: bool) -> Poll<()>

Shutdown service.

pub fn call(&self, req: In) -> <Apply<T, F, R, In, Out, Err> as Service>::Future

Process the request and return the response asynchronously.

fn map<F, R>(self, f: F) -> Map<Self, F, R> where
    F: FnMut(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) -> MapErr<Self, F, E> where
    F: Fn(Self::Error) -> E, 

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