TaskCoroutine

Overview:

TaskCoroutine wraps a generator and provides the internal execution model for Work.

Use TaskCoroutine inside cooperative workers where generator state and pass-through values must be tracked per task.

Public API:

• new TaskCoroutine($id, Generator $coroutine)
• id() returns the task ID.
• pass($value) provides a value for the next send.
• run() advances the generator.
• complete() returns true when the generator finishes.
