1.0.0[−][src]Struct std::sync::mpsc::Sender
The sending-half of Rust's asynchronous channel
type. This half can only be
owned by one thread, but it can be cloned to send to other threads.
Messages can be sent through this channel with send
.
Examples
use std::sync::mpsc::channel; use std::thread; let (sender, receiver) = channel(); let sender2 = sender.clone(); // First thread owns sender thread::spawn(move || { sender.send(1).unwrap(); }); // Second thread owns sender2 thread::spawn(move || { sender2.send(2).unwrap(); }); let msg = receiver.recv().unwrap(); let msg2 = receiver.recv().unwrap(); assert_eq!(3, msg + msg2);Run
Methods
impl<T> Sender<T>
[src]
pub fn send(&self, t: T) -> Result<(), SendError<T>>
[src]
Attempts to send a value on this channel, returning it back if it could not be sent.
A successful send occurs when it is determined that the other end of
the channel has not hung up already. An unsuccessful send would be one
where the corresponding receiver has already been deallocated. Note
that a return value of Err
means that the data will never be
received, but a return value of Ok
does not mean that the data
will be received. It is possible for the corresponding receiver to
hang up immediately after this function returns Ok
.
This method will never block the current thread.
Examples
use std::sync::mpsc::channel; let (tx, rx) = channel(); // This send is always successful tx.send(1).unwrap(); // This send will fail because the receiver is gone drop(rx); assert_eq!(tx.send(1).unwrap_err().0, 1);Run
