[−] Show declaration

pub enum TryRecvError {
    Empty,
    Disconnected,
}

[−] Expand description

An error returned from the try_recv method.

Variants

Empty

[−] Expand description

A message could not be received because the channel is empty.

If this is a zero-capacity channel, then the error indicates that there was no sender available to send a message at the time.

Disconnected

[−] Expand description

The message could not be received because the channel is empty and disconnected.
