A pointer type for a weak reference to an Objective-C reference counted object.
Methods
impl<T> WeakId<T> where
T: Message, [src]

pub fn new(obj: &ShareId<T>) -> WeakId<T>[src]
Construct a new WeakId referencing the given ShareId.
pub fn load(&self) -> Option<ShareId<T>>[src]
Load a ShareId from the WeakId if the object still exists.
Returns None if the object has been deallocated.
