Enum PacketTryRecvError 

#[non_exhaustive]
pub enum PacketTryRecvError {
    Empty,
    Disconnected,
}

Why PacketSinkReceiver::try_recv returned no event.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Empty

No event is currently queued.

Disconnected

The sending side is gone.
