    Self { name, age }
   }
}

let person_1 = Person::new(23, String::from("John"));
let person_2 = Person::new(19, String::from("Cynthia"));
let person_3 = Person::new(20, String::from("Luke"));

fn is_older_than_20(p: &Person) -> bool {
   p.age >= 20
}
let all_persons = vec![person_1, person_2, person_3];
let res = find_last_index::new(&all_persons, is_older_than_20)
println!("{res}") // Some(2)
}
