[dependabot]

Bumps pyo3 from 0.16.5 to 0.18.1.

Release notes

Sourced from pyo3's releases.

PyO3 0.18.1

This release fixes several bugs identified since PyO3 0.18.0, including a segfault and a Windows-specific issue with the PyIterator type, which would incorrectly accept any Python class regardless of whether it defined __next__ or not.

Some new APIs have been added such as PyErr::write_unraisable(), PyAny::is_ellipsis() and PyDict::update.

Thank you to the following users for the improvements:

PyO3 0.18.0

This release contains a number of new features for PyO3's macros which should make maintaining PyO3 projects easier.

#[pyfunction] and #[pymethods] have a new #[pyo3(signature = (...))] option which allows specifying the Python signature. This replaces the #[args] option already present for #[pymethods]; the new option is better-validated and offers a syntax much more intuitive to users familiar with writing pure-Python functions.

#[pyclass] has new get_all and set_all options for cases where all fields of a type should be readable or writable from Python.

The #[pyo3(text_signature = "...")] option is now autogenerated for all functions created with #[pyfunction] and #[pymethods]. It can still be applied manually when it is necessary to override the generated form.

As well as the macro API improvements, some other notable changes include:

• PySet::new and PyFrozenSet::new now accept Rust iterators rather than requiring a slice.
• Rust types have been added for all Python's built-in Warning types.
• Non-zero integer types in std::num now have a conversion to/from Python int.
• The deprecated #[pyproto] attribute is now removed.

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

Please consult the migration guide for help upgrading.
