无界通道

你可以使用 mpsc::channel() 获得无边界的异步通道:

  1. use std::sync::mpsc;
  2. use std::thread;
  3. use std::time::Duration;
  4. fn main() {
  5. let (tx, rx) = mpsc::channel();
  6. thread::spawn(move || {
  7. let thread_id = thread::current().id();
  8. for i in 1..10 {
  9. tx.send(format!("Message {i}")).unwrap();
  10. println!("{thread_id:?}: sent Message {i}");
  11. }
  12. println!("{thread_id:?}: done");
  13. });
  14. thread::sleep(Duration::from_millis(100));
  15. for msg in rx.iter() {
  16. println!("Main: got {msg}");
  17. }
  18. }
