It may also be used to fit a simple -operation on one line. -But when none of these apply, a simple `for` loop is more idiomatic. - -### Example -``` -let v = vec![0, 1, 2]; -v.iter().for_each(|elem| { - println!("{}", elem); -}) -``` -Use instead: -``` -let v = vec![0, 1, 2]; -for elem in v.iter() { - println!("{}", elem); -} -```
