Struct RecvError

Source 
pub struct RecvError;
🔬This is a nightly-only experimental API. (mpmc_channel)
Available on crate feature std only.
Expand description

An error returned from the recv function on a Receiver.

The recv operation can only fail if the sending half of a channel (or sync_channel) is disconnected, implying that no further messages will ever be received.
