idiomatic way of iterating through a collection using iterators only required number of times

Can somebody suggest an idiomatic way of iterating through the elements of a collection only required number of times. This is my code

fn main() {
    let list = vec![1, 3, 5, 7, 9, 11, 11, 11, 11, 13, 15, 17, 19];
    let mut count = 10;
    let mut itr = list.iter();
    while let Some(x) = itr.next() {
        if count > 0 {
            count -= 1;
            print!("{}, ", x);
        } else {
            break;
        }
    }
}

You're looking for take():

let list = vec![1, 3, 5, 7, 9, 11, 11, 11, 11, 13, 15, 17, 19];
for x in list.iter().take(10) {
    print!("{}, ", x);
}
