Trait Implementations

impl<R, E, F> Service for KeepAliveService<R, E, F>

where F: Fn() -> E,

type Request = R

Requests handled by the service.

type Response = R

Responses given by the service.

type Error = E

Errors produced by the service.

type Future = Ready<Result<R, E>>

The future response value.

fn poll_ready(&mut self, cx: &mut Context<'_>) -> Poll<Result<(), Self::Error>>

Returns Ready when the service is able to process requests.

fn call(&mut self, req: R) -> Self::Future

Process the request and return the response asynchronously.

fn map<F, R>(self, f: F) -> Map<Self, F, R>

where Self: Sized, F: FnMut(Self::Response) -> R,

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) -> MapErr<Self, F, E>

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

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