Class MappingRule (1.8.0) 

MappingRule(mapping=None, *, ignore_unknown_fields=False, **kwargs)

Definition of a transformation that is to be applied to a group of entities in the source schema. Several such transformations can be applied to an entity sequentially to define the corresponding entity in the target schema.

This message has oneof_ fields (mutually exclusive fields). For each oneof, at most one member field can be set at the same time. Setting any member of the oneof automatically clears all other members.
