Struct TestAsyncExecutorTaskWaiter 

pub struct TestAsyncExecutorTaskWaiter<T: Send> { /* private fields */ }

Waiter to be returned for top level Futures via TestAsyncExecutor::spawn().

A TestAsyncExecutorTaskWaiter provides a means to obtain the Output of the associated enqueued Future when Ready.

Note that a TestAsyncExecutorTaskWaiter implements Future itself, so it can get enqueued to the TestAsyncExecutor or polled from another owning Future.

Implementations

impl<T: Send> TestAsyncExecutorTaskWaiter<T>

pub fn take(self) -> Option<T>

Take the associated enqueued Future’s Output if Ready.

Returns None if the (future::Future::Output) is not Ready yet or the result has already been taken, including through Self::poll().

Trait Implementations

impl<T: Send> Drop for TestAsyncExecutorTaskWaiter<T>

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl<T: Send> Future for TestAsyncExecutorTaskWaiter<T>

type Output = T

The type of value produced on completion.

fn poll(self: Pin<&mut Self>, cx: &mut Context<'_>) -> Poll<Self::Output>

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