Struct ntex::service::dev::MapErrServiceFactory

pub struct MapErrServiceFactory<A, R, C, F, E> where
    A: ServiceFactory<R, C>,
    F: Fn(<A as ServiceFactory<R, C>>::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, R, C, F, E> Clone for MapErrServiceFactory<A, R, C, F, E> where
    A: ServiceFactory<R, C> + Clone,
    F: Fn(<A as ServiceFactory<R, C>>::Error) -> E + Clone, 

pub fn clone(&self) -> MapErrServiceFactory<A, R, C, F, E>

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

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

Responses given by the service

type Error = E

Errors produced by the service

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

The Service value created by this factory

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

Errors produced while building a service.

type Future = MapErrServiceFuture<A, R, C, F, E>

The future of the ServiceFactory instance.

pub fn new_service(
    &self,
    cfg: C
) -> <MapErrServiceFactory<A, R, C, F, E> as ServiceFactory<R, C>>::Future

Create and return a new service value asynchronously.

fn map<F, Res>(self, f: F) -> MapServiceFactory<Self, F, Req, Res, Cfg> where
    F: FnMut(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) -> MapErrServiceFactory<Self, Req, Cfg, F, E> where
    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, Req, Cfg, F, E> where
    F: Fn(Self::InitError) -> E + Clone, 

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