Enum TryRecvError 

pub enum TryRecvError {
    Empty,
    Disconnected,
}

Signals that a non-blocking attempt at receiving a value through a channel has failed. There are two possible reasons for this: (1) the message buffer of the channel is empty, or (2) the channel is closed.

Variants

Empty

attempt to receive a value has failed because the channel is empty

Disconnected

attempt to receive a value has failed because the channel is disconnected

Trait Implementations
