Trait Implementations

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

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

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

type Response = Out

Responses given by the service.

type Error = Err

Errors produced by the service when polling readiness or executing call.

type Future<'f>
where
    Self: 'f,
    In: 'f,
    R: 'f = R

The future response value.

fn poll_ready(&self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Ready when the service is able to process requests.

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

Shutdown service.

fn call(&self, req: In) -> Self::Future<'_>

Process the request and return the response asynchronously.

fn map<F, Res>(self, f: F) -> Map<Self, F, Req, Res>where
    Self: Sized,
    F: Fn(Self::Response) -> Res,

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, Req, F, E>where
    Self: Sized,
    F: Fn(Self::Error) -> E,

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