impl<T> Sender<T>
pub fn send(self, t: T) -> Result<(), T>
pub fn send(self, t: T) -> Result<(), T>
Completes this oneshot with a successful result.
This function will consume self and indicate to the other end, the
[Receiver], that the value provided is the result of the computation
this represents.
If the value is successfully enqueued for the remote end to receive,
then Ok(()) is returned. If the receiving end was dropped before
this function was called, however, then Err(t) is returned.
pub fn poll_canceled(&mut self, cx: &mut Context<'_>) -> Poll<()>
pub fn poll_canceled(&mut self, cx: &mut Context<'_>) -> Poll<()>
Polls this Sender half to detect whether its associated
[Receiver] has been dropped.
§Return values
If Ready(()) is returned then the associated Receiver has been
dropped, which means any work required for sending should be canceled.
If Pending is returned then the associated Receiver is still
alive and may be able to receive a message if sent. The current task,
however, is scheduled to receive a notification if the corresponding
Receiver goes away.
pub fn cancellation(&mut self) -> Cancellation<'_, T>
pub fn cancellation(&mut self) -> Cancellation<'_, T>
Creates a future that resolves when this Sender’s corresponding
[Receiver] half has hung up.
This is a utility wrapping poll_canceled
to expose a Future.
pub fn is_canceled(&self) -> bool
pub fn is_canceled(&self) -> bool
Tests to see whether this Sender’s corresponding Receiver
has been dropped.
Unlike poll_canceled, this function does not
enqueue a task for wakeup upon cancellation, but merely reports the
current state, which may be subject to concurrent modification.
pub fn is_connected_to(&self, receiver: &Receiver<T>) -> bool
pub fn is_connected_to(&self, receiver: &Receiver<T>) -> bool
Tests to see whether this Sender is connected to the given Receiver. That is, whether
they were created by the same call to channel.
