Updates the requirements on ndarray, ndarray-rand and linfa-datasets to permit the latest version.
Updates ndarray to 0.17.1

Changelog

Sourced from ndarray's changelog.

Version 0.17.1 (2025-11-02)

Version 0.17.1 provides a patch to fix the originally-unsound implementation of the new array reference types.

The reference types are now all unsized. Practically speaking, this has one major implication: writing functions and traits that accept RawRef and LayoutRef will now need a + ?Sized bound to work ergonomically with ArrayRef. For example, the release notes for 0.17.0 said

Reading / Writing Shape: LayoutRef<A, D>

LayoutRef lets functions view or modify shape/stride information without touching data. This replaces verbose signatures like:

fn alter_view<S>(a: &mut ArrayBase<S, Ix1>)
where S: Data<Elem = f64>;

Use AsRef / AsMut for best compatibility:

fn alter_shape<T>(a: &mut T)
where T: AsMut<LayoutRef<f64>>;

However, these functions now need an additional bound to allow for callers to pass in &ArrayRef types:

fn alter_shape<T>(a: &mut T)
where T: AsMut<LayoutRef<f64>> + ?Sized; // Added bound here

A huge thank you to Sarah Quiñones (@​sarah-quinones) for catching the original unsound bug and helping to fix it. She does truly excellent work with faer-rs; check it out!

Version 0.17.0 (2025-10-14) [YANKED]

Version 0.17.0 introduces a new array reference type — the preferred way to write functions and extension traits in ndarray.
This release is fully backwards-compatible but represents a major usability improvement.
The first section of this changelog explains the change in detail.

It also includes numerous new methods, math functions, and internal improvements — all credited below.

A New Way to Write Functions

TL;DR

ndarray 0.17.0 adds new reference types for writing functions and traits that work seamlessly with owned arrays and views.

When writing functions that accept array arguments:

  • Use &ArrayRef<A, D> to read elements from any array.
  • Use &mut ArrayRef<A, D> to modify elements.
  • Use &T where T: AsRef<LayoutRef<A, D>> to inspect shape/stride only.
  • Use &mut T where T: AsMut<LayoutRef<A, D>> to modify shape/stride only.

All existing function signatures continue to work; these new types are fully opt-in.

Updates ndarray-rand to 0.16.0

Release notes

Sourced from ndarray-rand's releases.

ndarray-rand 0.16.0

This release of ndarray-rand adds compatibility for the new ArrayRef type in ndarray 0.17. It adds the the new RandomRefExt trait, providing sample_axis and sample_axis_using methods on ArrayRef.

This release also bumps the requirements for rand to 0.9.0 and for rand_distr to 0.5.0.

Changelog

Version 0.16.0 (2024-08-03)

Featured Changes

  • Better shape: Deprecate reshape, into_shape by @​bluss #1310 .into_shape() is now deprecated. Use .into_shape_with_order() or .to_shape() instead, which don't have into_shape's drawbacks.
