Struct drone_core::sync::spsc::oneshot::Sender [−][src]
The sending-half of oneshot::channel
.
Implementations
impl<T> Sender<T>
[src]
pub fn send(self, data: T) -> Result<(), T>
[src]
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
is returned with the value
provided.
pub fn poll_canceled(&mut self, cx: &mut Context<'_>) -> Poll<()>
[src]
Polls this Sender
half to detect whether its associated
Receiver
with has been dropped.
Return values
If Ok(Ready)
is returned then the associated Receiver
has been
dropped, which means any work required for sending should be canceled.
If Ok(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 is_canceled(&self) -> bool
[src]
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.
