AlignedVec	A `Vec` wrapper with a memory alignment equal to Arrow’s primitive arrays. Can be useful in creating a new ChunkedArray or Arrow Primitive array without copying.
Arc	A thread-safe reference-counting pointer. ‘Arc’ stands for ‘Atomically Reference Counted’.
ArrowField	Contains the meta-data for a single relative type.
ArrowSchema	Describes the meta-data of an ordered sequence of relative types.
NumTakeRandomChunked
NumTakeRandomCont

ArrowPrimitiveType	Trait bridging the dynamic-typed nature of Arrow (via `DataType`) with the static-typed nature of rust types (`ArrowNativeType`) for all types that implement `ArrowNativeType`.
AsTakeIndex
ChunkAggSeries	Aggregations that return Series of unit length. Those can be used in broadcasting operations.
ChunkOps
IntoTakeRandom	Create a type that implements a faster `TakeRandom`.
LhsNumOps
NumOpsDispatch
NumOpsDispatchChecked
VarAggSeries
VecHash
