Bumps pyo3 from 0.21.2 to 0.22.3.

Release notes

Sourced from pyo3's releases.

PyO3 0.22.3

This release contains a number of quality improvements building upon PyO3 0.22.2.

Python function calls (using .call0(), .call1(args) and .call(args, kwargs)) will now make use of the "vectorcall" calling conventions where possible, which can reduce overheads in many cases.

There have been several fix-ups to PyO3's FFI definitions. A new pyo3::ffi::compat namespace has been added which offers some backwards-compatible implementations of Python APIs otherwise normally only available on recent Pythons.

There have been numerous other bug-fixes and minor tweaks to improve user experience.

Thank you to the following contributors for the improvements:

PyO3 0.22.2

This release contains some minor reliability fixes building upon PyO3 0.22.1.

As PyO3 is still working on supporting freethreaded Python (upcoming in 3.13), support has been gated behind an UNSAFE_PYO3_BUILD_FREE_THREADED=1 environment variable to avoid unsuspecting users running into broken builds.

Packages built for the abi3 stable ABI will now use FFI functions for refcounting instead of inline reference count modifications on all versions of the stable ABI (previously only abi3 builds for 3.12 and up would use FFI functions). This helps mitigate interactions of old versions of the stable ABI with future CPython releases which do more complex reference counting (e.g. immortal objects, freethreaded reference counting).

The #[pymodule] declarative module now supports directly receiving options. (E.g. #[pymodule(name = "foo")], which would previously have been written as two attributes #[pymodule] #[pyo3(name = "foo")].)

A compile error on Rust 1.78 related to use of c"" literals has been fixed.

PyO3 0.22.1

This patch release improves some cases related to new functionality in PyO3 0.22.

PartialEq<bool> has been added for Bound<'py, PyBool>.

The #[pyo3(submodule)] attribute has been added for declarative modules to stop submodules from generating an external C symbol for importing the submodule directly (which is typically never used). Declarative modules will also now correctly add items annotated with full-path attributes like #[pyo3::prelude::pyfunction].

The #[pyclass(eq)] option will no longer raise a TypeError on comparison against types not in the signature.
