| * Rendezvous channel. This channel does not have any buffer at all. An element is transferred from sender |
| * to receiver only when [send] and [receive] invocations meet in time (rendezvous), so [send] suspends |
| * until another coroutine invokes [receive] and [receive] suspends until another coroutine invokes [send]. |
| * |
| * Use `Channel()` factory function to conveniently create an instance of rendezvous channel. |
| * |
| * This implementation is fully lock-free. |
