Struct std::sync::mpsc::HandleUnstable
[-] [+]
[src]
pub struct Handle<'rx, T: 'rx> {
// some fields omitted
}A handle to a receiver which is currently a member of a Select set of
receivers. This handle is used to keep the receiver in the set as well as
interact with the underlying receiver.
Methods
impl<'rx, T: Send + 'static> Handle<'rx, T>
fn id(&self) -> usize
Retrieve the id of this handle.
fn recv(&mut self) -> Result<T, RecvError>
Block to receive a value on the underlying receiver, returning Some on
success or None if the channel disconnects. This function has the same
semantics as Receiver.recv
unsafe fn add(&mut self)
Adds this handle to the receiver set that the handle was created from. This
method can be called multiple times, but it has no effect if add was
called previously.
This method is unsafe because it requires that the Handle is not moved
while it is added to the Select set.
unsafe fn remove(&mut self)
Removes this handle from the Select set. This method is unsafe because
it has no guarantee that the Handle was not moved since add was
called.
