Implementations

impl<S, F> MapErr<S, F>

pub const fn new(inner: S, f: F) -> MapErr<S, F>

Creates a new MapErr service.

pub fn layer(f: F) -> MapErrLayer<F>

Returns a new Layer that produces MapErr services.

This is a convenience function that simply calls MapErrLayer::new.

Trait Implementations

impl<S, F> Clone for MapErr<S, F>

where S: Clone, F: Clone,

fn clone(&self) -> MapErr<S, F>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<S, F> Debug for MapErr<S, F>

where S: Debug,

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

Formats the value using the given formatter.

impl<S, F, Request, Error> Service<Request> for MapErr<S, F>

where S: Service<Request>, F: FnOnce(<S as Service<Request>>::Error) -> Error + Clone,

type Response = <S as Service<Request>>::Response

Responses given by the service.

type Error = Error

Errors produced by the service.

type Future = MapErrFuture<<S as Service<Request>>::Future, F>

The future response value.

fn poll_ready( &mut self, cx: &mut Context<'_>, ) -> Poll<Result<(), <MapErr<S, F> as Service<Request>>::Error>>

Returns Poll::Ready(Ok(())) when the service is able to process requests.

fn call( &mut self, request: Request, ) -> <MapErr<S, F> as Service<Request>>::Future

Process the request and return the response asynchronously.
