Trait PyClassWeakRef 

pub trait PyClassWeakRef: Sealed {
    const INIT: Self;

    // 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.

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".
