[][src]Struct actix_utils::oneshot::Receiver

#[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 unsync::oneshot::channel function and is equivalent in functionality to sync::oneshot::Receiver except that it cannot be sent across threads.

Methods

impl<T> Receiver<T>[src]

pub fn close(&mut self)[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.
