Add itertools 0.12 to Cargo.toml and import the Itertools trait to access advanced iterator methods.

Add itertools = "0.12" to your Cargo.toml dependencies and import the Itertools trait to unlock advanced iterator methods like with_position and commasep_exprs.

[dependencies]
itertools = "0.12"

use itertools::Itertraits;

let items = vec![1, 2, 3];
for (pos, item) in items.iter().with_position() {
    println!("{}: {}", pos, item);
}
