[−][src]Struct objc::rc::WeakPtr
A pointer that weakly references an object, allowing to safely check whether it has been deallocated.
Implementations
impl WeakPtr[src]
pub unsafe fn new(obj: *mut Object) -> Self[src]
Constructs a WeakPtr to the given object.
Unsafe because the caller must ensure the given object pointer is valid.
pub fn load(&self) -> StrongPtr[src]
Loads the object self points to, returning a StrongPtr.
If the object has been deallocated, the returned pointer will be null.
