Enum crossbeam_channel::TryRecvError

source · [−]

pub enum TryRecvError {
    Empty,
    Disconnected,
}

Expand description

An error returned from the try_recv method.

Variants

`Empty`

A message could not be received because the channel is empty.

If this is a zero-capacity channel, then the error indicates that there was no sender available to send a message at the time.

`Disconnected`

The message could not be received because the channel is empty and disconnected.

Implementations

source

impl TryRecvError

source

pub fn is_empty(&self) -> bool

Returns true if the receive operation failed because the channel is empty.

source

pub fn is_disconnected(&self) -> bool

Returns true if the receive operation failed because the channel is disconnected.
