Struct drone_core::sync::spsc::oneshot::Receiver [−][src]
The receiving-half of oneshot::channel
.
Implementations
impl<T> Receiver<T>
[src]
pub fn close(&mut self)
[src]
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.
pub fn try_recv(&mut self) -> Result<Option<T>, Canceled>
[src]
Attempts to receive a message outside of the context of a task.
Does not schedule a task wakeup or have any other side effects.
A return value of Ok(None)
must be considered immediately stale (out
of date) unless close
has been called first.
Returns an error if the sender was dropped.
