Function abi_stable::external_types::crossbeam_channel::bounded
source · pub fn bounded<T>(capacity: usize) -> (RSender<T>, RReceiver<T>)
Expand description
Creates a channel which can hold up to capacity
elements in its internal queue.
If capacity==0
,the value must be sent to a receiver in the middle of a recv
call.
§Panics
Panics if capacity >= usize::max_value() / 4
.
§Example
use abi_stable::external_types::crossbeam_channel as mpmc;
let (tx, rx) = mpmc::bounded::<u32>(3);
std::thread::spawn(move || {
tx.send(10).unwrap();
tx.send(11).unwrap();
tx.send(12).unwrap();
});
assert_eq!(rx.recv().unwrap(), 10);
assert_eq!(rx.recv().unwrap(), 11);
assert_eq!(rx.recv().unwrap(), 12);
assert!(rx.try_recv().is_err());
