Release notes

PyO3 0.12.1

This release contains a couple of bugfixes to resolve complation issues with 0.12.0 on specific targets. Thank you to @alex and @mtreinish for the bug reports and subsequent patches.

Fixed

• Fix building for a 32-bit Python on 64-bit Windows with a 64-bit Rust toolchain. #1179
• Fix building on platforms where c_char is u8. #1182

PyO3 0.12.0

This release includes a few careful revisions to the PyO3 API with the intention to make it easier to learn and use. The PyErr type is reworked to implement std::error::Error. The FromPy trait is removed. Finally, the PyObject struct is now just a type alias to Py<PyAny>. While we do not take pleasure in making breaking changes for users' code, we have done so with careful thought to make migration as simple as possible while also allowing the PyO3 API to mature. Please see the migration guide for help upgrading if any of these changes affect you.

Also added is a new #[derive(FromPyObject)] macro, which enables a convenient way to accept arguments of the Python "type" Union. (See the guide entry on this new feature.)

There have been many other improvements and bugfixes too numerous to go into detail here. For the full list, see the CHANGELOG.

Thank you to everyone who contributed code, documentation fixes, design ideas, bug reports, and feedback on the way to PyO3 0.12. The full list of users who commited at least one contribution to PyO3 0.12 is below:

• Add PyString::to_str for accessing PyString as &str. #1023
• Add Python::with_gil for executing a closure with the Python GIL. #1037
• Add type information to failures in PyAny::downcast(). #1050
• Implement Debug for PyIterator. #1051
• Add PyBytes::new_with and PyByteArray::new_with for initialising bytes and bytearray objects using a closure. #1074
• Add #[derive(FromPyObject)] macro for enums and structs. #1065
• Add Py::as_ref and Py::into_ref for converting Py<T> to &T. #1098
• Add ability to return Result types other than PyResult from #[pyfunction], #[pymethod] and #[pyproto] functions. #1106.
• Implement ToPyObject, IntoPy, and FromPyObject for hashbrown's HashMap and HashSet types (requires the hashbrown feature). #1114
• Add #[pyfunction(pass_module)] and #[pyfn(pass_module)] to pass the module object as the first function argument. #1143

• Add native PyCFunction and PyFunction types. #1163

Changed

• Rework exception types: #1024 #1115
  • Rename exception types from e.g. RuntimeError to PyRuntimeError. The old names continue to exist but are deprecated.
  • Exception objects are now accessible as &T or Py<T>, just like other Python-native types.
  • Rename PyException::py_err() to PyException::new_err().
  • Rename PyUnicodeDecodeErr::new_err() to PyUnicodeDecodeErr::new().
  • Remove PyStopIteration::stop_iteration().
• Require T: Send for the return value T of Python::allow_threads. #1036
• Rename PYTHON_SYS_EXECUTABLE to PYO3_PYTHON. The old name will continue to work (undocumented) but will be removed in a future release. #1039
• Remove unsafe from signature of PyType::as_type_ptr. #1047
• Change return type of PyIterator::from_object to PyResult<PyIterator> (was Result<PyIterator, PyDowncastError>). #1051
• IntoPy is no longer implied by FromPy. #1063
• Change PyObject to be a type alias for Py<PyAny>. #1063
• Rework PyErr to be compatible with the std::error::Error trait: #1067 #1115
  • Implement Display, Error, Send and Sync for PyErr and PyErrArguments.
  • Add PyErr::instance() for accessing PyErr as &PyBaseException.
  • PyErr's fields are now an implementation detail. The equivalent values can be accessed with PyErr::ptype(), PyErr::pvalue() and PyErr::ptraceback().
  • Change receiver of PyErr::print() and PyErr::print_and_set_sys_last_vars() to &self (was self).
  • Remove PyErrValue, PyErr::from_value, PyErr::into_normalized(), and PyErr::normalize().
  • Remove PyException::into().
  • Remove Into<PyResult<T>> for PyErr and PyException.
• Change methods generated by #[pyproto] to return NotImplemented if Python should try a reversed operation. #1072
• Change argument to PyModule::add to impl IntoPy<PyObject> (was impl ToPyObject). #1124

Removed

• Remove many exception and PyErr APIs; see the "changed" section above. #1024 #1067 #1115
• Remove PyString::to_string (use new PyString::to_str). #1023
• Remove PyString::as_bytes. #1023
• Remove Python::register_any. #1023
