Update pyo3 requirement from 0.18.1 to 0.19.0

[dependabot]

Updates the requirements on pyo3 to permit the latest version.

Release notes

Sourced from pyo3's releases.

PyO3 0.19.0

This release completes the implementation of automatically generated __text_signature__ for #[pymethods] and #[pyfunctions] by extending support for #[new] functions as well as rendering the value of simple default values such as integers, bools, and None in the generated signature.

Support for rust_decimal conversions to Python's decimal.Decimal has been added.

Usage of #[pyclass(frozen)] types becomes more powerful with the addition of Py::get to access contents of frozen classes without needing the Python GIL.

Some important fixes and removals have landed:

• __traverse__ implementations may no longer access Python APIs or acquire the Python GIL. Attempting to use Python::with_gil will panic.
• #[pyclass(unsendable)] types will now warn and skip Drop implementations when dropped on a thread other than the one the type was created on.
• The deprecated Python::acquire_gil has been 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.

Changelog

Sourced from pyo3's changelog.

[0.19.0] - 2023-05-31

Packaging

• Correct dependency on syn to version 1.0.85 instead of the incorrect version 1.0.56. #3152

Added

• Accept text_signature option (and automatically generate signature) for #[new] in #[pymethods]. #2980
• Add support for converting to and from Python's decimal.Decimal and rust_decimal::Decimal. #3016
• Add #[pyo3(from_item_all)] when deriving FromPyObject to specify get_item as getter for all fields. #3120
• Add pyo3::exceptions::PyBaseExceptionGroup for Python 3.11, and corresponding FFI definition PyExc_BaseExceptionGroup. #3141
• Accept #[new] with #[classmethod] to create a constructor which receives a (subtype's) class/PyType as its first argument. #3157
• Add PyClass::get and Py::get for GIL-indepedent access to classes with #[pyclass(frozen)]. #3158
• Add PyAny::is_exact_instance and PyAny::is_exact_instance_of. #3161

Changed

• PyAny::is_instance_of::<T>(obj) is now equivalent to T::is_type_of(obj), and now returns bool instead of PyResult<bool>. #2881
• Deprecate text_signature option on #[pyclass] structs. #2980
• No longer wrap anyhow::Error/eyre::Report containing a basic PyErr without a chain in a PyRuntimeError. #3004
• • Change #[getter] and #[setter] to use a common call "trampoline" to slightly reduce generated code size and compile times. #3029
• Improve default values for str, numbers and bool in automatically-generated text_signature. #3050
• Improve default value for None in automatically-generated text_signature. #3066
• Rename PySequence::list and PySequence::tuple to PySequence::to_list and PySequence::to_tuple. (The old names continue to exist as deprecated forms.) #3111
• Extend the lifetime of the GIL token returned by PyRef::py and PyRefMut::py to match the underlying borrow. #3131
• Safe access to the GIL, for example via Python::with_gil, is now locked inside of implementations of the __traverse__ slot. #3168

Removed

• Remove all functionality deprecated in PyO3 0.17, most prominently Python::acquire_gil is replaced by Python::with_gil. #2981

Fixed

• Correct FFI definitions PyGetSetDef, PyMemberDef, PyStructSequence_Field and PyStructSequence_Desc to have *const c_char members for name and doc (not *mut c_char). #3036
• Fix panic on fmt::Display, instead return "<unprintable object>" string and report error via sys.unraisablehook() #3062
• Fix a compile error of "temporary value dropped while borrowed" when #[pyfunction]s take references into #[pyclass]es #3142
• Fix crashes caused by PyO3 applying deferred reference count updates when entering a __traverse__ implementation. #3168
• Forbid running the Drop implementations of unsendable classes on other threads. #3176
• Fix a compile error when #[pymethods] items come from somewhere else (for example, as a macro argument) and a custom receiver like Py<Self> is used. #3178

[0.18.3] - 2023-04-13

Added

• Add GILProtected<T> to mediate concurrent access to a value using Python's global interpreter lock (GIL). #2975
• Support PyASCIIObject / PyUnicode and associated methods on big-endian architectures. #3015
• Add FFI definition _PyDict_Contains_KnownHash() for CPython 3.10 and up. #3088
