Struct CancelledFuture 

pub struct CancelledFuture { /* private fields */ }

A future that completes when a CancellationToken is cancelled.

• If the token is already cancelled, poll returns Poll::Ready immediately.
• Otherwise, the future registers its waker and returns Poll::Pending.

Single-threaded only. Not Send or Sync. The future will be woken exactly once when the token is cancelled.
