Struct futures::sync::oneshot::Receiver[][src]

#[must_use = "futures do nothing unless polled"]
pub struct Receiver<T> { /* fields omitted */ }

A future representing the completion of a computation happening elsewhere in memory.

This is created by the oneshot::channel function.

Methods

impl<T> Receiver<T>
[src]

Gracefully close this receiver, preventing sending any future messages.

Any send operation which happens after this method returns is guaranteed to fail. Once this method is called the normal poll method can be used to determine whether a message was actually sent or not. If Canceled is returned from poll then no message was sent.

Attempts to receive a message outside of the context of a task.

Useful when a Context is not available such as within a Drop impl.

Does not schedule a task wakeup or have any other side effects.

A return value of None must be considered immediately stale (out of date) unless ::close has been called first.

Returns an error if the sender was dropped.
