Struct std::sync::mpsc::Handle [] [src]

pub struct Handle<'rx, T: Send + 'rx> { /* fields omitted */ }
Unstable (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.

Retrieves the id of this handle.

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

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.

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.
