[dependabot]

Bumps pyo3 from 0.12.4 to 0.16.3.

Release notes

Sourced from pyo3's releases.

PyO3 0.16.3

This release contains a number of non-breaking additions and fixes since PyO3 0.16.2.

They are mostly centered on improving support for various build configurations. There are also usability tweaks to the #[pyclass] macro and a new intern! macro to create statically-backed PyString objects as an optimization technique.

Thank you to the following users for the improvements:

@​momirza @​ravenexp @​zh-jq

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:

@​adamreichold @​alex @​birkenfeld @​davidhewitt @​messense

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.

Thank you for the following users for the improvements:

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.
