Is the circuit built to this step? Must be one of:

  • CPATH_STATE_CLOSED (The circuit has not been extended to this step)
  • CPATH_STATE_AWAITING_KEYS (We have sent an EXTEND/CREATE to this step and not received an EXTENDED/CREATED)
  • CPATH_STATE_OPEN (The circuit has been extended to this step)
