Create a lists column of distinct elements found in either of two input lists columns.
null_equality
Enum to consider two nulls as equal or unequal.
nan_equality
Enum to consider different elements (of floating point types) holding NaN value as equal or unequal.
@ EQUAL
nulls compare equal
@ ALL_EQUAL
All NaNs compare equal, regardless of sign.
