Bumps pyo3 from 0.19.2 to 0.21.1.

Release notes

Sourced from pyo3's releases.

PyO3 0.21.1

This release is a set of touch-ups to PyO3 0.21 to fix cases found as adoption of PyO3 0.21.0 progressed.

The new PyBackedStr and PyBackedBytes types have had a large range of standard traits implemented, including Clone, PartialEq, Hash, PartialOrd, Display, Debug, Send and Sync.

The argument to a #[setter] function now accepts the full range of input types as any other function argument in a #[pymethods] block, and will now correctly handle a #[pyo3(from_py_with = "...")] annotation.

Some procedural macro output has been adjusted to reuse more code and make it easier to reach complete code coverage in projects using PyO3. The import_exception_bound! macro has been added to further assist with coverage during migration, by skipping generating code which is only needed to use the exception as a GIL Ref.

Finally, the experimental-async feature now correctly handles async fn in #[pymethods] which have a &self or &mut self receiver plus additional arguments.

Thank you to the following users for the improvements:

PyO3 0.21.0

This release introduces a substantial new direction for PyO3's API. The Bound<'py, T> smart pointer type has been added that replaces "GIL Refs" such as &'py PyAny and &'py PyList with smart-pointer forms Bound<'py, PyAny> and Bound<'py, PyList>. This new smart pointer brings ownership out of PyO3's internals and into user control. This has been done for sake of both performance and soundness.

The migration guide extensively details the intended transition to the new API. To allow users a more graceful upgrade path, PyO3 0.21 and 0.22 will maintain backwards compatibility support for the existing "GIL Refs" API.

As well as the Bound API, highlights of PyO3 0.21 include:

• Support for compiling for GraalPy
• Extended chrono / datetime conversions, including support for the abi3 feature and the chrono-tz crate
• Simplifications to __next__ and __anext__ methods

PyO3 0.21 also includes two new experimental features:

• experimental-async for a simple async fn integration between Rust and Python.
• experimental-declarative-modules for a new simpler #[pymodule] syntax.

There have been numerous other smaller improvements, changes and fixes. For full details see the CHANGELOG.

Please consult the migration guide for help upgrading.
