Trait pyo3::pyclass_slots::PyClassWeakRef

pub trait PyClassWeakRef {
    const IS_DUMMY: bool;

    fn new() -> Self;
    fn __private__(&self) -> PrivateMarker;

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

Represents the __weakref__ field for #[pyclass].

Associated Constants

const IS_DUMMY: bool

Whether this weakref type is capable of holding weak references.

Required methods

fn new() -> Self

Initializes a weakref instance.

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.
