Struct crossbeam::channel::SendError

pub struct SendError<T>(pub T);

An error returned from the send method.

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

The error contains the message so it can be recovered.

Methods

impl<T> SendError<T>

pub fn into_inner(self) -> T

Unwraps the message.

Examples

use crossbeam_channel::unbounded;

let (s, r) = unbounded();
drop(r);

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