Enum std::sync::mpsc::TryRecvError1.0.0[−][src]

pub enum TryRecvError {
    Empty,
    Disconnected,
}

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

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.
