Struct actix_net::service::MapErr

pub struct MapErr<A, F, E> where
    A: Service,
    F: Fn(A::Error) -> E,  { /* fields omitted */ }

Service for the map_err combinator, changing the type of a service's error.

This is created by the ServiceExt::map_err method.

Methods

impl<A, F, E> MapErr<A, F, E> where     A: Service,     F: Fn(A::Error) -> E,

pub fn new(service: A, f: F) -> Self

Create new MapErr combinator

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<A, F, E> Service for MapErr<A, F, E> where     A: Service,     F: Fn(A::Error) -> E,     F: Clone,

type Request = A::Request

Requests handled by the service.

type Response = A::Response

Responses given by the service.

type Error = E

Errors produced by the service.

type Future = MapErrFuture<A, F, E>

The future response value.

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

Returns Ready when the service is able to process requests.

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

Process the request and return the response asynchronously.

fn ready(self) -> Ready<Self>

A future yielding the service when it is ready to accept a request.
