Properties
resultAnchor
The result anchor of the async operation, or nil if the operation isn't completed successfully.
This should only be used after checking that state is GARFutureStateDone.
resultRooftopAnchorState
The result rooftop anchor state of the async operation, or a default value if the operation isn't complete.
This should only be used after checking that state is GARFutureStateDone.
