Struct pyo3::pyclass_slots::PyClassWeakRefSlot

source · [−]

#[repr(transparent)]
pub struct PyClassWeakRefSlot(_);

Expand description

Actual weakref field, which holds the pointer to __weakref__.

#[pyclass(weakref)] automatically adds this.

Trait Implementations

source

impl PyClassWeakRef for PyClassWeakRefSlot

source

const IS_DUMMY: bool = false

Whether this weakref type is capable of holding weak references.

source

fn new() -> Self

Initializes a weakref instance.

source

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

Clears the weak references to the given object. Read more

source

fn private(&self) -> PrivateMarker

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