send

fn send<T>(Sender tx, T value) -> Result<unit, ThreadError>

use thread::{send};

Sends a copy of value on the channel.

Never waits, since channels are unbounded. Returns Err(ThreadError::Disconnected) once the channel is closed and Err(ThreadError::NotSendable) for a value that cannot cross threads.

Parameters#

Returns#

Result<unit, ThreadError>

Examples#

use thread::{channel, send, recv};
use tests::assert;
let (tx, rx) = match channel() {
    Result::Ok(pair) => pair,
    Result::Err(_) => panic "channel failed",
};
let _ = send(tx, [1, 2, 3]);
let v = match recv(rx) {
    Result::Ok(v) => v,
    Result::Err(_) => [0, 0, 0],
};
assert!(v[2] == 3);
