Creates a channel; cap: 0 is a rendezvous channel (§8.7).

Example:

fn main() io {
  let (tx, rx) = chan<str>(cap: 4)
  tx.send("a")!
  tx.send("b")!
  print("{rx.recv()!}{rx.recv()!}")
}

Output

ab

@intrinsic("chan") pub(api) fn chan<T>(cap: usize = 0) -> (Sender<T>, Receiver<T>)

Complexity. O(1).

Since. 1.0.0-beta
