async fn ready( &self, _: ServiceCtx<'_, KeepAliveService<R, E, F>>, ) -> Result<(), <KeepAliveService<R, E, F> as Service<R>>::Error>

Returns when the service is able to process requests.

fn poll( &self, cx: &mut Context<'_>, ) -> Result<(), <KeepAliveService<R, E, F> as Service<R>>::Error>

Polls service from the current task.

async fn call( &self, req: R, _: ServiceCtx<'_, KeepAliveService<R, E, F>>, ) -> Result<R, E>

Process the request and return the response asynchronously.

async fn shutdown(&self)

Shutdown service.

fn map<F, Res>(self, f: F) -> ServiceChain<Map<Self, F, Req, Res>, Req>

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

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) -> ServiceChain<MapErr<Self, F, E>, Req>

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

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