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.

Implementations

`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.
