[−]pub struct MapErr<S, F> { /* private fields */ }Expand description
Service returned by the map_err combinator.
Implementations
impl<S, F> MapErr<S, F>
impl<S, F> MapErr<S, F>
pub fn layer(f: F) -> MapErrLayer<F>
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.
