Traits
- CategoricalMergeOperation
dtype-categorical
- Aggregations that return
Series
of unit length. Those can be used in broadcasting operations. - Safety
- NumOpsDispatchChecked
checked_arithmetic
- Utility trait to slice concrete arrow arrays whilst keeping their concrete type. E.g. don’t return
Box<dyn Array>
.
