无界通道
你可以使用 mpsc::channel()
获得无边界的异步通道:
use std::sync::mpsc;
use std::thread;
use std::time::Duration;
fn main() {
let (tx, rx) = mpsc::channel();
thread::spawn(move || {
let thread_id = thread::current().id();
for i in 1..10 {
tx.send(format!("Message {i}")).unwrap();
println!("{thread_id:?}: sent Message {i}");
}
println!("{thread_id:?}: done");
});
thread::sleep(Duration::from_millis(100));
for msg in rx.iter() {
println!("Main: got {msg}");
}
}
