Expert Answer
First of all you need to allow clone of enum Person by adding below code on top of enum Person definition:
#[derive(Clone)]
After this you add below line in place of //how can i access the ements of pieces here??
let mut i = 0;
while i < pieces.len() {
inspect(pieces[i].clone());
i += 1;
}
