Struct Take

#[repr(transparent)]
pub struct Take<C>(pub C);

Used to remove the value of a cell. Can be constructed directly or with AsyncCell::take.

Note that a single instance of Take can be used multiple times to consume a sequence of values. For example:

use async_cell::unsync::AsyncCell;

let cell = AsyncCell::new();
let taker = cell.take();

cell.set(1);
assert_eq!(taker.await, 1);

cell.set(2);
assert_eq!(taker.await, 2);

Trait Implementations

impl<C: Clone> Clone for Take<C>

fn clone(&self) -> Take<C>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, C> Future for &Take<C>

where C: Deref<Target = AsyncCell<T>>,

type Output = T

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<T>

Attempts to resolve the future to a final value, registering the current task for wakeup if the value is not yet available.
