Added

  • #[pyclass] objects can now be returned from rust functions
  • PyComplex by kngwyu in #226
  • PyDict::from_sequence(), equivalent to dict([(key, val), ...])
  • Bindings for the datetime standard library types: PyDate, PyTime, PyDateTime, PyTzInfo, PyDelta with associated ffi types, by pganssle #200.
  • PyString, PyUnicode, and PyBytes now have an as_bytes() method that returns &[u8].
  • PyObjectProtocol::get_type_ptr() by ijl in #242

Removed

  • Removed most entries from the prelude. The new prelude is small and clear.
  • Slowly removing specialization uses
  • PyString, PyUnicode, and PyBytes no longer have a data() method
    (replaced by as_bytes()) and PyStringData has been removed.

Changed

  • Removes the types from the root module and the prelude. They now live in pyo3::types instead.
  • All exceptions are consturcted with py_err instead of new, as they return PyErr and not Self.
  • as_mut and friends take and &mut self instead of &self
  • ObjectProtocol::call now takes an Option<&PyDict> for the kwargs instead of an IntoPyDictPointer.
  • IntoPyDictPointer was replace by IntoPyDict which doesn't convert PyDict itself anymore and returns a PyDict instead of *mut PyObject.
  • PyTuple::new now takes an IntoIterator instead of a slice
  • Updated to syn 0.15
  • Splitted PyTypeObject into PyTypeObject without the create method and PyTypeCreate with requires PyObjectAlloc<Self> + PyTypeInfo + Sized.
  • Ran cargo edition --fix which prefixed path with crate:: for rust 2018
  • Renamed async to pyasync as async will be a keyword in the 2018 edition.
  • Starting to use NonNull<*mut PyObject> for Py and PyObject by ijl #260

Fixed

  • Added an explanation that the GIL can temporarily be released even while holding a GILGuard.
  • Lots of clippy errors
  • Fix segfault on calling an unknown method on a PyObject
  • Work around a bug in the rust compiler by kngwyu #252
  • Fixed a segfault with subclassing pyo3 create classes and using __class__ by kngwyu #263

Removed

  • The pyobject_extract macro
