Previously, defining `__getattr__` would override all existing fields and methods. This changes it to behave like a `__getattr__` method defined in python, i.e. the custom method is only called if there isn't a field or method of that name
* Add `MODULE` const value to `PyTypeInfo` trait
* Allow setting module name in `pyclass` macro arguments
* Add `$module` argument to `pyobject_native_type` macro in `pyo3::types`
* Set the right module for builtin types in `pyo3::types`
* Add `module` argument to example `word_count.WordCounter` class
* Add `module` argument of `pyclass` macro to guide
* Reformat code using `rustfmt`
* Add tests and entry in CHANGELOG.md for `module` argument in `pyclass`
* Make `$module` parameter in `pyobject_native_type` optional
* Make `pyobject_native_type` declare module as `Some("builtins")` by default
* Removed a lot of clutter, unified some code
* Started using syn::parse::Parse for pyfunction attributes
* No more newlines between imports
* Renamed `#[prop(get, set)]` to `#[pyo3(get, set)]`
* `#[pyfunction]` now supports the same arguments as `#[pyfn()]`
* Some macros now emit proper spanned errors instead of panics.
* Renamed `py_exception` to `create_exception`
* The split up of the macros makes it possible to create exception structs with bodies to mimic python exceptions' members
* Used `Once` to fix a (theoretical) race condition with the is_null check
PyStringData comments mention wanting to receive interpreter-
specific unicode types. I tried implementing this, but it's
more complex and slower to call libpython to fill a buffer
of u32 or such and convert that in Rust using widestring.
This implementation receives UTF-8 from PyUnicode_AsUTF8AndSize()
in python3 and PyUnicode_AsUTF8String() in python2. PyStringData
is removed as unnecessary.
The data() method on PyString, PyBytes, and PyUnicode is
replaced with as_bytes().
The python2 API changes improve the performance of
extracting unicode strings.
