Struct objc::rc::WeakPtr

pub struct WeakPtr(_);

A pointer that weakly references an object, allowing to safely check whether it has been deallocated.

Methods

impl WeakPtr

pub unsafe fn new(obj: *mut Object) -> Self

Constructs a WeakPtr to the given object. Unsafe because the caller must ensure the given object pointer is valid.

pub fn load(&self) -> StrongPtr

Loads the object self points to, returning a StrongPtr. If the object has been deallocated, the returned pointer will be null.
