impl<A, B, St, Req> ServiceFactory<St, Req> for ThenFactory<A, B>

where A: ServiceFactory<St, Req>, B: ServiceFactory<St, Result<A::Res, A::Error>, Error = A::Error, InitError = A::InitError>,

type Res = <B as ServiceFactory<St, Result<<A as ServiceFactory<St, Req>>::Res, <A as ServiceFactory<St, Req>>::Error>>>::Res

Responses given by the created services.

type Error = <A as ServiceFactory<St, Req>>::Error

Errors produced by the created services.

type Service = Then<<A as ServiceFactory<St, Req>>::Service, <B as ServiceFactory<St, Result<<A as ServiceFactory<St, Req>>::Res, <A as ServiceFactory<St, Req>>::Error>>>::Service>

The type of Service produced by this factory.

type InitError = <A as ServiceFactory<St, Req>>::InitError

Possible errors encountered during service construction.

async fn create(&self, st: &St) -> Result<Self::Service, Self::InitError>

Creates a new service asynchronously and returns it.

async fn pipeline( &self, st: St, ) -> Result<Pipeline<Req, Self::Res, Self::Error>, Self::InitError>

where Self: 'static, St: 'static, Req: 'static,

Asynchronously creates a new service and wraps it in a container.

fn map<F, Res>( self, f: F, ) -> ServiceChainFactory<MapFactory<F, Self, Res>, St, Req>

where Self: Sized, F: Fn(Self::Res) -> Res + Clone,

Returns a new service that maps this service’s output to a different type.

fn map_err<F, E>( self, f: F, ) -> ServiceChainFactory<MapErrFactory<F, Self, E>, St, Req>

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

Transforms this service’s error into another error, producing a new service.

fn map_init_err<F, E>( self, f: F, ) -> ServiceChainFactory<MapInitErr<F, Self, E>, St, Req>

where Self: Sized, F: Fn(Self::InitError) -> E + Clone,

Maps this factory’s initialization error to a different error, returning a new service factory.

fn and_then<U, F>( self, f: F, ) -> ServiceChainFactory<AndThenFactory<Self, U>, St, Req>

where Self: Sized, U: ServiceFactory<St, Self::Res, Error = Self::Error, InitError = Self::InitError>, F: IntoServiceFactory<U, St, Self::Res>,

Call another service after call to this one has resolved successfully.

fn boxed( self, ) -> BoxServiceFactory<St, Req, Self::Res, Self::Error, Self::InitError>

where St: 'static, Req: 'static, Self: Sized + 'static,

Creates a boxed service factory.
