Struct `MapErr`

struct MapErr<S, F> { ... }

Service returned by the map_err combinator.

Implementations

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

const fn new(inner: S, f: F) -> Self

Creates a new MapErr service.

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

Returns a new Layer that produces MapErr services.

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