Struct tower::util::MapResponse

pub struct MapResponse<S, F> { /* private fields */ }

Service returned by the map_response combinator.

Implementations

impl<S, F> MapResponse<S, F>

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

Creates a new MapResponse service.

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

Returns a new Layer that produces MapResponse services.

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

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

where S: Debug,

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

Formats the value using the given formatter.

impl<S, F, Request, Response> Service<Request> for MapResponse<S, F>
