Update pyo3 requirement from 0.17 to 0.18
Updates the requirements on pyo3 to permit the latest version.
Release notes
Sourced from pyo3's releases.
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 newget_allandset_alloptions 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::newandPyFrozenSet::newnow accept Rust iterators rather than requiring a slice.- Rust types have been added for all Python's built-in
Warningtypes.- Non-zero integer types in
std::numnow have a conversion to/from Pythonint.- 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.
