Struct std::sync::mpsc::Handle
[−]
[src]
pub struct Handle<'rx, T: Send + 'rx> { // some fields omitted }
: 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
`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
: 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
Retrieves the id of this handle.
fn recv(&mut self) -> Result<T, RecvError>
: 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
`Someon success or
` on
success or None
`Noneif the channel disconnects. This function has the same semantics as
` if the channel disconnects. This function has the same
semantics as Receiver.recv
`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
`add` was
called previously.
This method is unsafe because it requires that the Handle
`Handleis not moved while it is added to the
` is not moved
while it is added to the Select
`Select` set.
unsafe fn remove(&mut self)
: 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
`Selectset. This method is unsafe because it has no guarantee that the
` set. This method is unsafe because
it has no guarantee that the Handle
`Handlewas not moved since

`add` was
called.
