rustHow to iterate in pairs in Rust

Iterating in pairs in Rust can be done using the .zip() method. This method takes two iterators and returns a new iterator of pairs. The following example code will print out the pairs of numbers from two separate vectors:

let v1 = vec![1, 2, 3];
let v2 = vec![4, 5, 6];

for (a, b) in v1.iter().zip(v2.iter()) {
    println!("{} {}", a, b);
}

Output example

1 4
2 5
3 6

Code explanation

• let v1 = vec![1, 2, 3];: creates a vector v1 with the elements 1, 2, 3
• let v2 = vec![4, 5, 6];: creates a vector v2 with the elements 4, 5, 6
• for (a, b) in v1.iter().zip(v2.iter()): creates a loop that iterates over the pairs of elements from v1 and v2
• println!("{} {}", a, b);: prints out the elements of each pair
