Struct CancellationWaiter 

pub struct CancellationWaiter { /* private fields */ }

A race-safe future resolving to the immutable terminal reason.

It holds only a weak token reference and unregisters its stored waker when dropped.

Trait Implementations

impl Debug for CancellationWaiter

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

Formats the value using the given formatter.

impl Drop for CancellationWaiter

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 Future for CancellationWaiter

type Output = CancellationReason

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.
