pub enum TryRecvError {
    Empty,
    Closed,
    Lagged(u64),
}
Available on crate feature sync only.
Expand description

An error returned from the try_recv function on a Receiver.

Variants§

§

Empty

The channel is currently empty. There are still active Sender handles, so data may yet become available.

§

Closed

There are no more active senders implying no further messages will ever be sent.

§

Lagged(u64)

The receiver lagged too far behind and has been forcibly disconnected. Attempting to receive again will return the oldest message still retained by the channel.

Includes the number of skipped messages.
