pub struct Sender<T> { /* private fields */ }🔬This is a nightly-only experimental API. (
oneshot_channel)Expand description
The sending half of a oneshot channel.
§Examples
#![feature(oneshot_channel)]
use std::sync::oneshot;
use std::thread;
let (sender, receiver) = oneshot::channel();
thread::spawn(move || {
sender.send("Hello from thread!").unwrap();
});
assert_eq!(receiver.recv().unwrap(), "Hello from thread!");Sender cannot be sent between threads if it is sending non-Send types.

let (sender, receiver) = oneshot::channel();
struct NotSend(*mut ());
thread::spawn(move || {
sender.send(NotSend(ptr::null_mut()));

🔬This is a nightly-only experimental API. (oneshot_channel)
pub fn send(self, t: T) -> Result<(), SendError<T>>
oneshot_channel)Attempts to send a value through this channel. This can only fail if the corresponding
Receiver<T> has been dropped.
This method is non-blocking (wait-free).
§Examples
#![feature(oneshot_channel)]
use std::sync::oneshot;
use std::thread;
let (tx, rx) = oneshot::channel();
thread::spawn(move || {
// Perform some computation.
let result = 2 + 2;
tx.send(result).unwrap();
});
assert_eq!(rx.recv().unwrap(), 4);Trait Implementations§
