Struct Get

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

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

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

use async_cell::unsync::AsyncCell;

let cell = AsyncCell::new();
let getter = cell.get();

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

Trait Implementations

impl<C: Clone> Clone for Get<C>

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

Returns a copy of the value.

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

Performs copy-assignment from source.

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

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

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.

impl<T, C> Future for Get<C>
