// in rust, generic are more about what you want to do than on what you are
// trying to do it, therefore you probably should constraint your generic
// on the specific operations you require for your code. If you really need
// to constrait on integral types you could use the num crate
// but it is likely overkill
// example of generic function over additive types:
fn example<T1, T2, R>(a:T1, b:T2) -> R
where
	//we only require to be able to add a T2 to a T1
    T1: std::ops::Add<T2, Output = R>,
{
    return a + b;
}
