class_docstr: A debugging context manager.
  
  Without an active debugging context, devices will not save their internal state when
  encoutering Snapshot operations. The debugger also serves as storage for the device states.
  
  Args:
      dev (Device): device to attach the debugger to
code: def __exit__(self, exc_type, exc_value, exc_traceback):
      self.active = False
      self.device._debugger = None
  
imports: import pennylane
  from pennylane import DeviceError
label_desc: Use image node_id 3 for calling the _Debugger obj's underlying member method code with example usage: obj.__exit__(exc_type, exc_value, exc_traceback) without return types
