TryRecvError

mina_core::channels::mpsc

Enum TryRecvError 

pub enum TryRecvError {
    Empty,
    Disconnected,
}
Expand description

An error that may be emitted when attempting to fetch a value on a receiver when there are no messages in the channel. If there are no messages in the channel and all senders are dropped, then TryRecvError::Disconnected will be returned.

Variants§

§

Empty

The channel was empty when the receive was attempted.

§

Disconnected

All senders were dropped and no messages are waiting in the channel, so no further messages can be received.
