Changelog

  • Unreleased

  • v0.17.0

    • Add dynamic borrow checking to safely construct references into the interior of NumPy arrays. (#274)
      • The deprecated iterator builders NpySingleIterBuilder::{readonly,readwrite} and NpyMultiIterBuilder::add_{readonly,readwrite} now take referencces to PyReadonlyArray and PyReadwriteArray instead of consuming them.
      • The destructive PyArray::resize method is now unsafe if used without an instance of PyReadwriteArray. (#302)
    • Add support for datetime64 and timedelta64 element types via the datetime module. (#308)
    • Add support for IEEE 754-2008 16-bit floating point numbers via an optional dependency on the half crate. (#314)
    • The inner, dot and einsum functions can also return a scalar instead of a zero-dimensional array to match NumPy's types (#285)
    • The PyArray::resize function supports n-dimensional contiguous arrays. (#312)
    • Deprecate PyArray::from_exact_iter after optimizing PyArray::from_iter. (#292)
    • Remove DimensionalityError and TypeError from the public API as they never used directly. (#315)
    • Remove the deprecated PyArrayDescr::get_type which was replaced by PyArrayDescr::typeobj in the last cycle. (#308)
    • Fix returning invalid slices from PyArray::{strides,shape} for rank zero arrays. (#303)

  • v0.16.2

    • Fix build on platforms where c_char is u8 like Linux/AArch64. (#296)

  • v0.16.1

    • Fix build when PyO3's multiple-pymethods feature is used. (#288)

  • v0.16.0

    • Bump PyO3 version to 0.16 (#259)
    • Support object arrays (#216)
    • Support borrowing arrays that are part of other Python objects via PyArray::borrow_from_array (#230)
    • Fixed downcasting ignoring element type and dimensionality (#265)
    • PyArray::new is now unsafe, as it produces uninitialized arrays (#220)
    • PyArray::iter, NpySingleIterBuilder::readwrite and NpyMultiIterBuilder::add_readwrite are now unsafe, as they allow aliasing mutable references to be created (#278/)
    • The npyiter module is deprecated as rust-ndarray's facilities for iteration are more flexible and performant (#280)
    • PyArray::from_exact_iter does not unsoundly trust ExactSizeIterator::len any more (#262)
    • PyArray::as_cell_slice was removed as it unsoundly interacts with PyReadonlyArray allowing safe code to violate aliasing rules (#260)
    • rayon feature is now removed, and directly specifying the feature via ndarray dependency is recommended (#250)
    • Element trait and PyArrayDescr changes (#256):
      • Element trait has been simplified to get_dtype() and IS_COPY
      • New PyArrayDescr methods: of, into_dtype_ptr, is_equiv_to
      • Added numpy::dtype function
      • Element is now implemented for isize
      • c32 / c64 have been renamed with Complex32 / Complex64
      • ShapeError has been split into TypeError and DimensionalityError
      • i32, i64, u32, u64 are now guaranteed to map to np.u?int{32,64}.
      • Removed cfg_if dependency
      • Removed DataType enum
    • Added PyArrayDescr::new constructor (#266)
    • New PyArrayDescr methods (#266):
      • num, base, ndim, shape, byteorder, char, kind, itemsize, alignment, flags, has_object, is_aligned_struct, names, get_field, has_subarray, has_fields, is_native_byteorder
      • Renamed get_type to typeobj
