Struct tower::util::MapErr[][src]

pub struct MapErr<S, F> { /* fields omitted */ }
This is supported on crate feature util only.

Service returned by the map_err combinator.


impl<S, F> MapErr<S, F>[src]

pub fn new(inner: S, f: F) -> Self[src]

Creates a new MapErr service.

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

Returns a new Layer that produces MapErr services.

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