Struct devela::_deps::std::sync::mpsc::RecvError

1.0.0 · source · 
pub struct RecvError;
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.
