There's really not much to understand there. The difference from mixin is that Base can inherit an interface so that Derived exposes the interface just by deriving from Base.

class Base(Derived)
{
    void interface()
    {
        // ...
        (cast(Derived)this).implementation();
        // ...
    }
 
    static void static_func()
    {
        // ...
        Derived.static_sub_func();
        // ...
    }
}
 
class Derived : Base!(Derived)
{
    void implementation(){...}
    static void static_sub_func(){...}
}
