Struct ntex_service::dev::AndThen

pub struct AndThen<A, B> { /* private fields */ }

Service for the and_then combinator, chaining a computation onto the end of another service which completes successfully.

This is created by the ServiceExt::and_then method.

Trait Implementations

impl<A, B> Clone for AndThen<A, B>where
    A: Clone,
    B: Clone,

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A, B, Req> Service<Req> for AndThen<A, B>where
    A: Service<Req>,
    B: Service<A::Response, Error = A::Error>,

type Response = <B as Service<<A as Service<Req>>::Response>>::Response

Responses given by the service.

type Error = <A as Service<Req>>::Error

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

type Future<'f>
where
    Self: 'f,
    Req: 'f = AndThenServiceResponse<'f, A, B, Req>

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: Req) -> 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.
