pub trait ListModelExtManual: Sized {
// Required methods
fn snapshot(&self) -> Vec<Object>;
fn iter<T: IsA<Object>>(&self) -> ListModelIter<'_, T>;
}
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
.
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.
