Enum std::sync::mpsc::TryRecvError

[+] Show declaration

pub enum TryRecvError {
    Empty,
    Disconnected,
}

[−] Expand description

This enumeration is the list of the possible reasons that try_recv could not return data when called. This can occur with both a channel and a sync_channel.

Variants

Empty

[−] Expand description

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

Disconnected

[−] Expand description

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