Struct ntex_service::dev::MapErrServiceFactory

pub struct MapErrServiceFactory<A, F, E> where
    A: ServiceFactory,
    F: Fn(A::Error) -> E + Clone,  { /* fields omitted */ }

Factory for the map_err combinator, changing the type of a new service’s error.

This is created by the NewServiceExt::map_err method.

Trait Implementations

impl<A, F, E> Clone for MapErrServiceFactory<A, F, E> where
    A: ServiceFactory + Clone,
    F: Fn(A::Error) -> E + 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, F, E> ServiceFactory for MapErrServiceFactory<A, F, E> where
    A: ServiceFactory,
    F: Fn(A::Error) -> E + 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 Config = A::Config

Service factory configuration

type Service = MapErr<A::Service, F, E>

The Service value created by this factory

type InitError = A::InitError

Errors produced while building a service.

type Future = MapErrServiceFuture<A, F, E>

The future of the ServiceFactory instance.

fn new_service(&self, cfg: A::Config) -> Self::Future

Create and return a new service value asynchronously.

fn map<F, R>(self, f: F) -> MapServiceFactory<Self, F, R> where
    Self: Sized,
    F: FnMut(Self::Response) -> R + Clone, 

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) -> MapErrServiceFactory<Self, F, E> where
    Self: Sized,
    F: Fn(Self::Error) -> E + Clone, 

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

fn map_init_err<F, E>(self, f: F) -> MapInitErr<Self, F, E> where
    Self: Sized,
    F: Fn(Self::InitError) -> E + Clone, 

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