Enum crossbeam_channel::TrySendError

[−] Show declaration

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

[−] Expand description

An error returned from the try_send method.

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

Variants

Full(T)

[−] Expand description

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)

[−] Expand description

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

Implementations

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.
