I am trying to have the Data struct implement the Main (and the other two super traits). However, I cannot get it to work. It works fine if Super2 had no generic type. I tried impl with generic without generic. Any help will be appreciated. Thank you.

trait Super1 {
    fn super_fun1();
}

trait Super2<T> {
    fn super_fun2(source: T);
}

trait Main<T>: Super1 + Super2<T> {
    fn main_fun();
}

struct Data(f64);

impl Main for Data {
    fn main_fun() {}
}

impl Super1 for Data {
    fn super_fun1() {}
}

impl Super2<String> for Data {
    fn super_fun2(source: String) {}
}

I tried placing in different places for Data implementation.
