Enum TryRecvError

pub enum TryRecvError {
    Empty,
    Disconnected,
}

Available on crate feature sync only.

Error returned by Receiver::try_recv.

Variants

Empty

This channel is currently empty, but the Sender(s) have not yet disconnected, so data may yet become available.

Disconnected

The channel’s sending half has become disconnected, and there will never be any more data received on it.
