Struct Sender

pub struct Sender<T> { /* private fields */ }

The sending half of a channel.

Implementations

impl<T> Sender<T>

pub fn send(&mut self, t: T) -> Result<(), SendError<T>>

Send data to the corresponding Receiver.

This may block if the underlying syscall blocks, namely if the pipe buffer is full.

Errors

If the corresponding Receiver is already dropped, this method will return Err(SendError(t)), transferring the ownership over t back to the caller.

Examples

Success:

use std::thread;
use pipe_channel::*;

let (mut tx, mut rx) = channel();
let handle = thread::spawn(move || {
    tx.send(35).unwrap();
    tx.send(42).unwrap();
});
assert_eq!(rx.recv().unwrap(), 35);
assert_eq!(rx.recv().unwrap(), 42);
handle.join().unwrap();

Failure:

use pipe_channel::*;
use std::sync::mpsc::SendError;
use std::mem::drop;

let (mut tx, rx) = channel();
drop(rx);
assert_eq!(tx.send(42), Err(SendError(42)));
