Struct ntex_service::dev::MapErrFactory

pub struct MapErrFactory<A, R, C, F, E>where
    A: ServiceFactory<R, C>,
    F: Fn(A::Error) -> E + Clone,{ /* private fields */ }

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, R, C, F, E> Clone for MapErrFactory<A, R, C, F, E>where A: ServiceFactory<R, C> + 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, R, C, F, E> ServiceFactory<R, C> for MapErrFactory<A, R, C, F, E>where A: ServiceFactory<R, C>, F: Fn(A::Error) -> E + Clone,

type Response = <A as ServiceFactory<R, C>>::Response

Responses given by the created services.

type Error = E

Errors produced by the created services.

type Service = MapErr<<A as ServiceFactory<R, C>>::Service, F, E>

The kind of Service created by this factory.

type InitError = <A as ServiceFactory<R, C>>::InitError

Errors potentially raised while building a service.

type Future<'f> = MapErrFactoryFuture<'f, A, R, C, F, E> where Self: 'f, C: 'f

The future of the ServiceFactory instance.

fn create(&self, cfg: C) -> Self::Future<'_>

Create and return a new service value asynchronously.

fn pipeline(&self, cfg: Cfg) -> CreatePipeline<'_, Self, Req, Cfg> where Self: Sized,

Create and return a new service value asynchronously and wrap into a container

fn map<F, Res>( self, f: F ) -> ServiceChainFactory<MapFactory<Self, F, Req, Res, Cfg>, Req, Cfg>where Self: Sized, F: Fn(Self::Response) -> Res + 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 ) -> ServiceChainFactory<MapErrFactory<Self, Req, Cfg, F, E>, Req, Cfg>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 ) -> ServiceChainFactory<MapInitErr<Self, Req, Cfg, F, E>, Req, Cfg>where Self: Sized, F: Fn(Self::InitError) -> E + Clone,

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