Bumps pyo3 from 0.15.1 to 0.16.3.

Release notes

Sourced from pyo3's releases.

PyO3 0.16.2

This release contains support for the latest PyPy 7.3.8 release, a fix for a regression from PyO3 0.16.0 which would cause flaky build failures, and corrections to documentation.

Thank you for the following users for the improvements:

PyO3 0.16.1

This release contains a couple of fixes for regressions in PyO3 0.16.0, as well as documentation fixes. The hashbrown optional dependency range has been extended to include its new 0.12 version.

PyO3 0.16.0

This release contains substantial changes and improvements over PyO3 0.15.1. To support these improvements, support has been dropped for the end-of-life Python 3.6 and Rust versions older than 1.48.

The pyo3::ffi submodule has been split out into a separate pyo3-ffi crate, so that users who want to use PyO3's Python bindings without any of the safe APIs or macros are able to do so.

#[pyclass] can now be used on simple "C-like" enums to create Python enums.

The #[pyproto] macro has been deprecated, and can be disabled by disabling the optional #[pyproto] feature. The "magic methods" such as __repr__ which previously were implemented by #[pyproto] gained support in #[pymethods] in 0.15, and now in PyO3 0.16 #[pymethods] is intended to be the only attribute macro needed to write class method implementations.

There are numerous other reworks, improvements, and bugfixes.

For full details of all changes, see the CHANGELOG.

Thank you to everyone who contributed code, documentation, design ideas, bug reports, and feedback. The following users' commits are included in this release:

[Unreleased]

Added

• Add PYO3_CROSS_PYTHON_IMPLEMENTATION environment variable for selecting the default cross Python implementation. #2272
• Add new public pyo3-build-config API using the types from target_lexicon crate. Deprecate cross_compiling(). #2253
• Allow dependent crates to access config values from pyo3-build-config via cargo link dep env vars. #2092
• Added methods on InterpreterConfig to run Python scripts using the configured executable. #2092
• Added FFI definitions for PyType_FromModuleAndSpec, PyType_GetModule, PyType_GetModuleState and PyModule_AddType. #2250
• Add PyString::intern to enable usage of the Python's built-in string interning. #2268
• Add intern! macro which can be used to amortize the cost of creating Python strings by storing them inside a GILOnceCell. #2269

Changed

• Make PYO3_CROSS_LIB_DIR environment variable optional when cross compiling. #2241
• Allow #[pyo3(crate = "...", text_signature = "...")] options to be used directly in #[pyclass(crate = "...", text_signature = "...")]. #2234
• Mark METH_FASTCALL calling convention as limited API on Python 3.10. #2250

Fixed

• Fix abi3-py310 feature: use Python 3.10 ABI when available instead of silently falling back to the 3.9 ABI. #2242
• Considered PYTHONFRAMEWORK when cross compiling in order that on macos cross compiling against a Framework bundle is considered shared. #2233
• Panic during compilation when PYO3_CROSS_LIB_DIR is set for some host/target combinations. #2232
• Correct dependency version for syn to require correct minimal patch version 1.0.56. #2240

Added

• Added as_bytes on Py<PyBytes>. #2235
• Add #[pyclass(mapping)] option to leave sequence slots empty in container implementations. #2265

Packaging

• Extend parking_lot dependency supported versions to include 0.12. #2239

[0.16.2] - 2022-03-15

Packaging

• Warn when modules are imported on PyPy 3.7 versions older than PyPy 7.3.8, as they are known to have binary compatibility issues. #2217
• Ensure build script of pyo3-ffi runs before that of pyo3 to fix cross compilation. #2224

[0.16.1] - 2022-03-05
