How can I zip more than two iterators?

Question

Is there a more direct and readable way to accomplish the following:

fn main() {
    let a = [1, 2, 3];
    let b = [4, 5, 6];
    let c = [7, 8, 9];
    let         


        

Answer 1

I wanted to be able to do this to an arbitrarily long vector, so I had to implement this by hand:

fn transpose_records(records: &Vec>) -> Vec> {
    let mut transposed: Vec> = vec![Vec::new(); records[0].len()];

    for record in records {
        for (index, element) in record.iter().enumerate() {
            transposed[index].push(element.clone());
        }
    }

    transposed
}
