Description:
 def _parse_log_entry(entry_pb):
 """Special helper to parse ``LogEntry`` protobuf into a dictionary. The ``proto_payload`` field in ``LogEntry`` is of type ``Any``. This can be problematic if the type URL in the payload isn't in the ``google.protobuf`` registry. To help with parsing unregistered types, this function will remove ``proto_payload`` before parsing. :type entry_pb: :class:`.log_entry_pb2.LogEntry` :param entry_pb: Log entry protobuf. :rtype: dict :returns: The parsed log entry. The ``protoPayload`` key may contain the raw ``Any`` protobuf from ``entry_pb.proto_payload`` if it could not be parsed. """
