PyO3: Python解释器的Rust绑定

konstin released this Mar 28, 2019 · 3 commits to master since this release

Currently, #341 causes cargo test to fail with weird linking errors when the extension-module feature is activated. For now you can work around this by making the extension-module feature optional and running the tests with cargo test --no-default-features:

[dependencies.pyo3]
version = "0.6.0"

[features]
extension-module = ["pyo3/extension-module"]
default = ["extension-module"]

Added a wrap_pymodule! macro similar to the existing wrap_pyfunction! macro. Only available on python 3
Added support for cross compiling (e.g. to arm v7) by mtp401 in #327. See the "Cross Compiling" section in the "Building and Distribution" chapter of the guide for more details.
The PyRef and PyRefMut types, which allow to differentiate between an instance of a rust struct on the rust heap and an instance that is embedded inside a python object. By kngwyu in #335
Added FromPy<T> and IntoPy<T> which are equivalent to From<T> and Into<T> except that they require a gil token.
Added ManagedPyRef, which should eventually replace ToBorrowedObject.

Renamed PyObjectRef to PyAny in #388
Renamed add_function to add_wrapped as it now also supports modules.
Renamed #[pymodinit] to #[pymodule]
py.init(|| value) becomes Py::new(value)
py.init_ref(|| value) becomes PyRef::new(value)
py.init_mut(|| value) becomes PyRefMut::new(value).
PyRawObject::init is now infallible, e.g. it returns () instead of PyResult<()>.
Renamed py_exception! to create_exception! and refactored the error macros.
Renamed wrap_function! to wrap_pyfunction!
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.
Migrated to the 2018 edition
crate::types::exceptions moved to crate::exceptions
Replace IntoPyTuple with IntoPy<Py<PyTuple>>.
IntoPyPointer and ToPyPointer moved into the crate root.
class::CompareOp moved into class::basic::CompareOp
PyTypeObject is now a direct subtrait PyTypeCreate, removing the old cyclical implementation in #350
Add PyList::{sort, reverse} by chr1sj0nes in #357 and #358
Renamed the typeob module to type_object

A soudness hole where every instances of a #[pyclass] struct was considered to be part of a python object, even though you can create instances that are not part of the python heap. This was fixed through PyRef and PyRefMut.
Fix kwargs support in #328.
Add full support for __dict__ in #403.

#[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 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.

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

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
