Sınırsız Kanallar
You get an unbounded and asynchronous channel with mpsc::channel()
:
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 0..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}"); } }
This slide should take about 2 minutes.
- An unbounded channel will allocate as much space as is necessary to store pending messages. The
send()
method will not block the calling thread. - A call to
send()
will abort with an error (that is why it returnsResult
) if the channel is closed. A channel is closed when the receiver is dropped.
