Trait Implementations

impl<F, E> Clone for KeepAlive<F, E>

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

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<F, E> Debug for KeepAlive<F, E>

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

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<F, E, St, Req> ServiceFactory<St, Req> for KeepAlive<F, E>

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

type Res = Req

Responses given by the created services.

type Error = E

Errors produced by the created services.

type Service = KeepAliveService<F, E>

The type of Service produced by this factory.

type InitError = !

Possible errors encountered during service construction.

async fn create(&self, _: &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.
