[Question] DiffUtil for ModelAdapter (like in ModelItemActivity)?

About this issue
I am trying to figure out how to use FastAdapterDiffUtil when using GenericModelAdapter.
Let's use as an example ModelItemActivity. It has IconModel, which does not extend GenericItem. I have the exact same situation in my code.
How to calculate Diff in ModelItemActivity when you have a list of IconModels for adapter which is ModelAdapter?
All FastAdapterDiffUtil calculateDiff methods require that provided items must extend GenericItem 😕

@Mariius the FastAdapterDiffUtil takes a ModelAdapter.
The GenericModelAdapter is just a specific variant of the ModelAdapter e.g. with the generic types pre-filled for you
typealias GenericModelAdapter<Model> = ModelAdapter<Model, GenericItem>The type should be dependent on the adapter you use with it. as you can see the GenericItem is just a base type alias with the lowest possible generic type
typealias GenericItem = IItem<out RecyclerView.ViewHolder>the DiffUtilActivity for example does it with SimpleItem
