Enum crossbeam::channel::TrySendError

pub enum TrySendError<T> {
    Full(T),
    Disconnected(T),
}

An error returned from the try_send method.

The error contains the message being sent so it can be recovered.

Variants

Full(T)

The message could not be sent because the channel is full.

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

Disconnected(T)

The message could not be sent because the channel is disconnected.

Methods

impl<T> TrySendError<T>

pub fn into_inner(self) -> T

Unwraps the message.

Examples

use crossbeam_channel::bounded;

let (s, r) = bounded(0);

if let Err(err) = s.try_send("foo") {
    assert_eq!(err.into_inner(), "foo");
}

pub fn is_full(&self) -> bool

Returns true if the send operation failed because the channel is full.

pub fn is_disconnected(&self) -> bool

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