Arrow to ndarray conversions (zero-copy views).

This module provides zero-copy conversions from Arrow arrays to ndarray views. All conversions borrow the Arrow buffer and produce ndarray views — no allocation occurs.

Null handling

Three tiers of null handling are provided:

• AsNdarray::as_ndarray — validates no nulls, returns Result. O(1).
• AsNdarray::as_ndarray_unchecked — caller guarantees no nulls. Zero cost.
• AsNdarray::as_ndarray_masked — returns view + optional validity bitmap. Zero allocation.

Traits

AsNdarray

Zero-copy conversion from an Arrow array to an ndarray view.

Functions

fixed_size_list_as_array2

Zero-copy conversion from a FixedSizeListArray to an ArrayView2.

fixed_size_list_as_array2_masked

Zero-copy conversion from a FixedSizeListArray to an ArrayView2 with a validity bitmap.

fixed_size_list_as_array2_unchecked^⚠

Zero-copy conversion from a FixedSizeListArray to an ArrayView2, without null checks.
