Please make this code work

struct Person {
    name: String,
    age: u32,
    hobby: String,
}

impl Person {
    fn new(name: &str, age: u32, hobby: &str) -> Self {
        Self {
            name: name.to_string(),
            age,
            hobby: hobby.to_string(),
        }
    }
}

fn main() {
    let people = [
        Person::new("John", 26, "Music"),
        Person::new("Kyle", 22, "Coding"),
        Person::new("Tommy", 17, "-"),
    ];
    
    for (person, i) in people {
      println!("index: {}, name: {}, age: {}, hobby: {}", i, person.name, person.age, person.hobby);
      //println!("name: {}, age: {}, hobby: {}", person.name, person.age, person.hobby);
    };
}

Here's a version on the playground.

struct Person {
    name: String,
    age: u32,
    hobby: String,
}

impl Person {
    fn new(name: &str, age: u32, hobby: &str) -> Self {
        Self {
            name: name.to_string(),
            age,
            hobby: hobby.to_string(),
        }
    }
}

fn main() {
    let people = [
        Person::new("John", 26, "Music"),
        Person::new("Kyle", 22, "Coding"),
        Person::new("Tommy", 17, "-"),
    ];
    
    for (index, person) in people.iter().enumerate() {
      let Person { name, age, hobby } = person;
      println!("index: {index}, name: {name}, age: {age}, hobby: {hobby}");
    }
}

Note that this line:

let Person { name, age, hobby } = person;

is short-hand for this:

let name = &person.name;
let age = &person.age;
let hobby = &person.hobby;
