Struct objc2::rc::Allocated

#[repr(transparent)]
pub struct Allocated<T: ?Sized>(_);

A marker type that can be used within Id to indicate that the object has been allocated but not initialized.

The reason we use Option<Id<Allocated<T>, O>> instead of just *mut T is:

• To allow releasing allocated objects, e.g. in the face of panics.
• To safely know the object is valid (albeit uninitialized).
• To allow specifying ownership.
