v0.15.0

Compare Source

===========================

New features

  Note that this means that a new trait bound is required in some places when
  mixing dimensionality types of arrays in arithmetic operations.

  https://github.com/rust-ndarray/ndarray/pull/898

• New methods slice_each_axis/_mut/_inplace that make it easier to slice
  a dynamic number of axes in some situations, by [@​jturner314]

  https://github.com/rust-ndarray/ndarray/pull/913

• New method a.assign_to(b) with the inverse argument order compared to the
  existing b.assign(a) and some extra features like assigning into
  uninitialized arrays, By [@​bluss].

  [@​kdubovikov]

  [@​jturner314]

  https://github.com/rust-ndarray/ndarray/pull/890

API changes

  No new functionality, just that these constructors are available without trait
  imports.

  https://github.com/rust-ndarray/ndarray/pull/921

• NdProducer::raw_dim is now a documented method by [@​jturner314]

  https://github.com/rust-ndarray/ndarray/pull/918

  [@​jturner314]. Its accessor methods are now deprecated.

  https://github.com/rust-ndarray/ndarray/pull/915

• Methods for array comparison abs_diff_eq and relative_eq are now
  exposed as inherent methods too (no trait import needed), still under the approx
  feature flag by [@​bluss]

  https://github.com/rust-ndarray/ndarray/pull/946

• Changes to the slicing-related types and macro by [@​jturner314] and [@​bluss]:

  • Remove the Dimension::SliceArg associated type, and add a new SliceArg
    trait for this purpose.
  • Change the return type of the s![] macro to an owned SliceInfo rather
    than a reference.
  • Replace the SliceOrIndex enum with SliceInfoElem, which has an
    additional NewAxis variant and does not have a step_by method.
  • Change the type parameters of SliceInfo in order to support the NewAxis
    functionality and remove some tricky unsafe code.
  • Mark the SliceInfo::new method as unsafe. The new implementations of
    TryFrom can be used as a safe alternative.
  • Remove the AsRef<SliceInfo<[SliceOrIndex], D>> for SliceInfo<T, D>
    implementation. Add the similar From<&'a SliceInfo<T, Din, Dout>> for SliceInfo<&'a [SliceInfoElem], Din, Dout> conversion as an alternative.
  • Change the expr ; step case in the s![] macro to error at compile
    time if an unsupported type for expr is used, instead of panicking at
    runtime.
