build: Bump the cargo group with 3 updates

[dependabot]

Bumps the cargo group with 3 updates: pyo3, rand and thiserror.

Updates pyo3 from 0.29.0 to 0.29.2

Release notes

Sourced from pyo3's releases.

PyO3 0.29.2

This patch fixes a regression in PyO3 0.29.1 which broke PyPy 3.11 compatibility (#[pyclass] types would crash PyPy on instance deletion).

A few further fixes have also landed with similar themes to PyO3 0.29.1: fixes to minor reference counting bugs, rough edges which would cause crashes, issues which would cause failed builds, and fixes to experimental-inspect type stub generation.

For a full list of the exact fixes please consult the CHANGELOG.

Thank you to the following contributors for the improvements:

PyO3 0.29.1

This patch is a stack of fixes for PyO3 0.29. Particular themes include:

• Fixes addressing build failures with newer interpreters such as GraalPy 3.13 and CPython 3.15
• Fixes resolving potential memory leaks inside #[pyclass] implementation internals
• Fixes to the new experimental-inspect type stub machinery

For a full list of the fixes in these above themes and more, please consult the CHANGELOG.

Packaging

• Add PYO3_USE_RAW_DYLIB=0 opt-out of raw-dylib linking for Windows. #6185

Fixed

• Fix PyO3 0.29 regression with failure to link under Cygwin / MSYS2. #6185
• Fix stubs generation for field getters (#[pyo3(get)]) when IntoPyObject is only implemented on references of the field type. #6276
• Fix #[classmethod] magic methods receiving the instance instead of its type when invoked through a type slot. #6283
• Fix pyo3_build_config::add_libpython_rpath_link_args emitting Unix-style rpath linker arguments on Windows and Cygwin. #6284
• Fix PyO3 0.29.1 regression on PyPy causing crashes when deallocating #[pyclass] instances. #6294
• Fix missing trailing nul in Python 3.9 #[pyclass] docstrings. #6296

[0.29.1] - 2026-08-02

Changed

• Use the inline definition of Py_TYPE in the unlimited API on 3.14+ #6179

Fixed

• Fix incorrect pointer arithmetic in FFI definitions PyObject_GET_WEAKREFS_LISTPTR and PyHeapType_GET_MEMBERS. #6145
• Fix compilation error with nightly feature on PyPy and GraalPy due to !Ungil implementations for FFI types not available on those platforms. #6146
• Fix append_to_inittab and PyInit_<module> internal module definition corruption on 32-bit and big-endian platforms on Python 3.15+. #6150
• Fix return value of PyClassGuardMutSuper::as_super being scoped to the full guard lifetime, now the &mut borrow of the as_super() call. #6181
• Fix builds for free-threaded interpreters older than 3.15 erroring with "cannot set a minimum Python version" when an abi3t-py3* feature is enabled and the configuration comes from PYO3_CONFIG_FILE, sysconfigdata or cross-compilation defaults. #6192
• Fix a memory leak when deallocating #[pyclass(dict)] instances with a populated __dict__. #6198
• Fix an abort inside a #[pyclass]'s GC traversal when the traversal is stopped early. #6206
• Fix reference cycles through the __dict__ of a #[pyclass(dict)] never being collected. #6206
• Fix building on GraalPy 3.13. #6208
• Fix reference count leak of references to #[pyclass] type objects held by their instances on instance deallocation. #6224
• Fix FFI definitions PyByteArray_GET_SIZE, PyList_GET_SIZE, and PySet_GET_SIZE to use an atomic load for free-threaded Python. #6230
• Fix a memory leak on Python 3.11 and 3.12 where creating an instance of a #[pyclass(dict)] class leaked one empty dict per instance. #6234
• Fix experimental-inspect type stubs to emit the arguments of many magic methods as positional-only to match runtime behavior, rather than positional-or-keyword. #6239
• Fix experimental-inspect type stubs to emit the Python name rather than the Rust name for #[pyfunction(name = "...")]. #6254
• Fix experimental-inspect generating invalid internal JSON when #[pymodule] members are gated by #[cfg]. #6255
• Fix __inplace_concat__ and __inplace_repeat__ overriding __concat__ and __repeat__ when both were defined. #6260
• Fix conversion of out-of-range time::Duration values to return OverflowError instead of panicking. #6266
• Fix experimental-inspect type stubs padding blank lines inside indented docstrings. #6270

Updates rand from 0.9.5 to 0.10.1

Changelog

Sourced from rand's changelog.

[0.10.1] — 2026-02-11

This release includes a fix for a soundness bug; see #1763.

Changes

• Document panic behavior of make_rng and add #[track_caller] (#1761)
• Deprecate feature log (#1763)

#1761: rust-random/rand#1761 #1763: rust-random/rand#1763

[0.10.0] - 2026-02-08

Changes

• The dependency on rand_chacha has been replaced with a dependency on chacha20. This changes the implementation behind StdRng, but the output remains the same. There may be some API breakage when using the ChaCha-types directly as these are now the ones in chacha20 instead of rand_chacha (#1642).
• Rename fns IndexedRandom::choose_multiple -> sample, choose_multiple_array -> sample_array, choose_multiple_weighted -> sample_weighted, struct SliceChooseIter -> IndexedSamples and fns IteratorRandom::choose_multiple -> sample, choose_multiple_fill -> sample_fill (#1632)
• Use Edition 2024 and MSRV 1.85 (#1653)
• Let Fill be implemented for element types, not sliceable types (#1652)
• Fix OsError::raw_os_error on UEFI targets by returning Option<usize> (#1665)
• Replace fn TryRngCore::read_adapter(..) -> RngReadAdapter with simpler struct RngReader (#1669)
• Remove fns SeedableRng::from_os_rng, try_from_os_rng (#1674)
• Remove Clone support for StdRng, ReseedingRng (#1677)
• Use postcard instead of bincode to test the serde feature (#1693)
• Avoid excessive allocation in IteratorRandom::sample when amount is much larger than iterator size (#1695)
• Rename os_rng -> sys_rng, OsRng -> SysRng, OsError -> SysError (#1697)
• Rename Rng -> RngExt as upstream rand_core has renamed RngCore -> Rng (#1717)

Additions

• Add fns IndexedRandom::choose_iter, choose_weighted_iter (#1632)
• Pub export Xoshiro128PlusPlus, Xoshiro256PlusPlus prngs (#1649)
• Pub export ChaCha8Rng, ChaCha12Rng, ChaCha20Rng behind chacha feature (#1659)
• Fn rand::make_rng() -> R where R: SeedableRng (#1734)

Removals

• Removed ReseedingRng (#1722)
• Removed unused feature "nightly" (#1732)
• Removed feature small_rng (#1732)
