PyO3 v0.9.0-alpha.1 Release Notes

Release Date: 2020-01-18 // over 4 years ago

  • PyO3 0.9.0 Alpha.1

    There are some breaking changes...
    But I believe in most cases, you just change this

    impl MyClass { #[new] fn new(init: &PyRawObject) { init.init(MyClass {}); } }

    to

    impl MyClass { #[new] fn new() -\> Self { MyClass {} } }

    and everything works fine.

    Please read the guide for detail.

    🔄 CHANGELOG

    🔄 Changed

    • The blanket implementations for FromPyObject for &T and &mut T are no longer specializable. Implement PyTryFrom for your type to control the behavior of FromPyObject::extract() for your types.
    • The implementation for IntoPy<U> for T where U: FromPy<T> is no longer specializable. Control the behavior of this via the implementation of FromPy.
    • #[new] does not take PyRawObject and can reutrn Self#683
    • 👉 Use parking_lot::Mutex instead of spin::Mutex #734
