A channel is a synchronization primitive.

Threads

You can use Venice in multi-threaded programs. However, individual threads are strictly separated. You may think of each thread as a separate process.

In particular, a coroutine created in a thread will be executed in that same thread, and it will never migrate to a different one.

In a similar manner, a handle, such as a channel or a coroutine handle, created in one thread cannot be used in a different thread.

Example:

let channel = Channel<Int>()

let coroutine = try Coroutine {
    try channel.send(42, deadline: 1.second.fromNow())
}

let theAnswer = try channel.receive(deadline: 1.second.fromNow())
try coroutine.close()
