Struct crossbeam_channel::SendError

[+] Show declaration

pub struct SendError<T>(pub T);

[−] Expand description

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.

Implementations

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");
}
