class NoneTypeLieGroupOps(*args, **kwds)[source]#

Bases: AbstractVectorLieGroupOps[None]

Class for implementing ops on None object. This is primarily used when performing ops on dataclasses with optional fields which could be None.

abstract_vector_lie_group_ops lets us only implement the StorageOps functions, and use those functions to perform Group and LieGroup ops.
