pub struct Receiver<T> { /* private fields */ }
Expand description
A future for a value that will be provided by another asynchronous task.
This is created by the channel
function.
Implementations§
source§impl<T> Receiver<T>
impl<T> Receiver<T>
sourcepub fn close(&mut self)
pub fn close(&mut self)
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.
sourcepub fn try_recv(&mut self) -> Result<Option<T>, Canceled>
pub fn try_recv(&mut self) -> Result<Option<T>, Canceled>
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 None
must be considered immediately stale (out of
date) unless close
has been called first.
Returns an error if the sender was dropped.
