States

Any coroutine instance is in one of the following states, which can be checked with the state variable:

• Ready - running or just created with runSuspended(...) and not yet tick()ed.
• Suspended - suspended with a suspend() call (or similar).
• Accepting - waiting for a value after an accept() call.
• Yielding - waiting to provide a value with a yield(...) call.
• Expecting - waiting for a value after a custom accept call.
• Terminated - finished, cannot be woken up again.

Return value

If a coroutine terminated with a return statement, the returned value is available in the returned field. Otherwise, the field is set to null. Coroutines that return Void will have returned with a type of pecan.Void.

var adder = pecan.Co.co(function():String {
  var x = accept();
  var y = accept();
  return '$x + $y = ${x + y}';
}, (_ : Int));

var instance = adder.run();
instance.give(1);
instance.give(2);
trace(instance.returned); // output: 1 + 2 = 3
