Struct spacegate_kernel::helper_layers::map_future::MapFuture

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

Service returned by the [map_future] combinator.

Implementations

impl<S, F> MapFuture<S, F>

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

Creates a new MapFuture service.

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

Returns a new Layer that produces MapFuture services.

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

pub fn get_ref(&self) -> &S

Get a reference to the inner service

pub fn get_mut(&mut self) -> &mut S

Get a mutable reference to the inner service

pub fn into_inner(self) -> S

Consume self, returning the inner service

Trait Implementations

impl<S: Clone, F: Clone> Clone for MapFuture<S, F>

fn clone(&self) -> MapFuture<S, F>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

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

where S: Debug,

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

Formats the value using the given formatter.

impl<R, S, F, T, E, Fut> Service<R> for MapFuture<S, F>

where S: Service<R>, F: Fn(S::Future) -> Fut, E: From<S::Error>, Fut: Future<Output = Result<T, E>>,

type Response = T

Responses given by the service.

type Error = E

Errors produced by the service.

type Future = Fut

The future response value.

fn call(&self, req: R) -> Self::Future

Process the request and return the response asynchronously. call takes &self instead of mut &self because:
