Struct std::sync::mpsc::Handle
[−]
[src]
pub struct Handle<'rx, T: Send + 'rx> { // some fields omitted }
mpsc_select
#27800): This implementation, while likely sufficient, is unsafe and likely to be error prone. At some point in the future this module will likely be replaced, and it is currently unknown how much API breakage that will cause. The ability to select over a number of channels will remain forever, but no guarantees beyond this are being made
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> Handle<'rx, T>
fn id(&self) -> usize

The ability to select over a number of channels will remain forever, but no guarantees beyond this are being made
Retrieves the id of this handle.
fn recv(&mut self) -> Result<T, RecvError>

#27800): This implementation, while likely sufficient, is unsafe and likely to be error prone. At some point in the future this module will likely be replaced, and it is currently unknown how much API breakage that will cause. The ability to select over a number of channels will remain forever, but no guarantees beyond this are being made
Blocks 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)
mpsc_select
#27800): This implementation, while likely sufficient, is unsafe and likely to be error prone. At some point in the future this module will likely be replaced, and it is currently unknown how much API breakage that will cause. The ability to select over a number of channels will remain forever, but no guarantees beyond this are being made
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)
mpsc_select
#27800): This implementation, while likely sufficient, is unsafe and likely to be error prone. At some point in the future this module will likely be replaced, and it is currently unknown how much API breakage that will cause. The ability to select over a number of channels will remain forever, but no guarantees beyond this are being made
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.
