Struct MapRequest

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

Composes a function in front of the service.

This adapter produces a new service that passes each value through the given function f before sending it to self.

Implementations

impl<S, F> MapRequest<S, F>

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

Creates a new MapRequest service.

pub fn get_ref(&self) -> &S

Gets a reference to the underlying service.

pub fn into_inner(self) -> S

Consumes self, returning the underlying service.
