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

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

A future for a value that will be provided by another asynchronous task.

This is created by the channel function.


impl<T> Receiver<T>


Gracefully close this receiver, preventing any subsequent attempts to send to it.

Any send operation which happens after this method returns is guaranteed to fail. After calling this method, you can use Receiver::poll to determine whether a message had previously been 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A return value of None must be considered immediately stale (out of date) unless ::close has been called first.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.
