Trait PyClassWeakRef

pub trait PyClassWeakRef {
    const INIT: Self;

    // Required method
    fn __private__(&self) -> PrivateMarker;

    // Provided method
    unsafe fn clear_weakrefs(&mut self, _obj: *mut PyObject, _py: Python<'_>) { ... }
}

Represents the __weakref__ field for #[pyclass].

Required Associated Constants

const INIT: Self

Initializes a weakref instance.

Required Methods

fn __private__(&self) -> PrivateMarker

This trait is private to implement; this method exists to make it impossible to implement outside the crate.

Provided Methods

unsafe fn clear_weakrefs(&mut self, _obj: *mut PyObject, _py: Python<'_>)

Clears the weak references to the given object.

Safety

• _obj must be a pointer to the pyclass instance which contains self.
• The GIL must be held.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
