Struct actix_service::dev::ThenService

pub struct ThenService<A, B> { /* fields omitted */ }

Service for the then combinator, chaining a computation onto the end of another service.

This is created by the ServiceExt::then method.

Trait Implementations

impl<A, B> Clone for ThenService<A, B> where
    A: 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> Service for ThenService<A, B> where
    A: Service,
    B: Service<Request = Result<A::Response, A::Error>, Error = A::Error>, 

type Request = A::Request

Requests handled by the service.

type Response = B::Response

Responses given by the service.

type Error = B::Error

Errors produced by the service.

type Future = ThenServiceResponse<A, B>

The future response value.

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

Returns Ready when the service is able to process requests.

fn call(&mut self, req: A::Request) -> Self::Future

Process the request and return the response asynchronously.

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

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