| /** |
| * A "proxy" class that simply forwards values, completion, and errors from its input writer to its |
| * writeable. |
| * It is useful as a superclass for pipes that act as a transformation of their |
| * input writer, and for classes that represent objects with input and |
| * output sequences of values, like an RPC. |
| * |
| * Thread-safety: |
| * All messages sent to this object need to be serialized. When it is started, the writer it wraps |
| * is started in the same thread. Manual state changes are propagated to the wrapped writer in the |
| * same thread too. Importantly, all messages the wrapped writer sends to its writeable need to be |
| * serialized with any message sent to this object. |
