Module arrays 

Built-in array encodings.

Canonical arrays are the default uncompressed representation for a logical dtype: NullArray, BoolArray, PrimitiveArray, DecimalArray, VarBinViewArray, ListViewArray, FixedSizeListArray, StructArray, ExtensionArray, and VariantArray.

Utility and lazy arrays represent common transformations without immediately materializing their result. Examples include ChunkedArray for concatenation, ConstantArray for repeated values, DictArray for dictionary encoding, FilterArray for masked rows, SliceArray for views, and ScalarFnArray for deferred scalar-function execution.

Some public arrays are primarily internal building blocks. Their constructors and extension traits document the stable contract; avoid depending on undocumented slot order or metadata details.
