impl<F, S, St, Req, Err> ServiceFactory<St, Req> for FnFactory<F, S, St, Req, Err>

where F: AsyncFn(&St) -> Result<S, Err>, S: Service<St, Req>,

type Res = <S as Service<St, Req>>::Res

Response produced by the created services.

type Error = <S as Service<St, Req>>::Error

Error produced by the created services.

type Service = S

The type of Service produced by this factory.

type InitError = Err

Error that can occur while constructing a service.

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

Asynchronously creates a service using the supplied state.

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

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

Creates a service and wraps it with its state in a Pipeline.

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 factory whose services map responses 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,

Returns a factory whose services map errors to a different type.

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,
