Required Methods§


fn snapshot(&self) -> Vec<Object>

Get an immutable snapshot of the container inside the ListModel. Any modification done to the returned container Vec will not be reflected on the ListModel.


fn iter<T: IsA<Object>>(&self) -> ListModelIter<'_, T>

If T::static_type().is_a(self.item_type()) then it returns an iterator over the ListModel elements, else the types are not compatible and returns an Err(...).


Panics if T::static_type().is_a(self.item_type()) is not true.
