Advanced Functional Programming with Elixir: persistence abstractions

In your great book you use structs as abstraction for your domain objects.
I understand, that you don’t want any dependencies.

But there are already abstractions which you can use in elixir.

  1. Ecto
  2. Ash-Framework, where you use the abstraction resource

In which way would I use them?

Thank you for writing this very interesting book.
