12. Enumerate

Use enumerate to convert iterator over (usize,item) pairs.

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
let cars = vec!["Skoda", "Ferrari", "Ford"];

for (idx, car) in cars.iter().enumerate() {
    println!("{idx} - {car}");
}

// Output
// 0 - Skoda
// 1 - Ferrari
// 2 - Ford

Useful when index of item is needed.
