Implementations

impl<Fut> Inner<Fut>where Fut: Future,

unsafe fn output(&self) -> &Fut::Output

Safety: callers must first ensure that self.inner.state is COMPLETE

impl<Fut> Inner<Fut>where Fut: Future, Fut::Output: Clone,

fn record_waker(&self, waker_key: &mut usize, cx: &mut Context<'_>)

Registers the current task to receive a wakeup when we are awoken.

unsafe fn take_or_clone_output(self: Arc<Self>) -> Fut::Output

Safety: callers must first ensure that inner.state is COMPLETE
