NonNullableStructVector.StructTransferPair	TransferPair for this this class.
StateTool	Utility methods for state machines based on enums.
StructVector	A Struct vector consists of nullability/validity buffer and children vectors that make up the struct's fields.
UnionVector
VectorWithOrdinal	Tuple of a ValueVector and an index into a data structure containing the ValueVector.
