Not fully-related, but I googled the question "convert interface struct to pointer" and get here.

So, just make a note: to convert an interface of T to interface of *T:

//
// Return a pointer to the supplied struct via interface{}
//
func to_struct_ptr(obj interface{}) interface{} {
    vp := reflect.New(reflect.TypeOf(obj))
    vp.Elem().Set(reflect.ValueOf(obj))
    return vp.Interface()
}
