rustHow to zip maps in Rust?


Zipping maps in Rust is a simple process. To do so, you can use the zip method from the Iterator trait. This method takes two iterators and returns a new iterator of pairs, where the first element of each pair is taken from the first iterator, and the second element is taken from the second iterator.

let map1 = [1, 2, 3];
let map2 = [4, 5, 6];

let zipped_map = map1.iter().zip(map2.iter());

for pair in zipped_map {
    println!("{:?}", pair);
}

Output example

(1, 4)
(2, 5)
(3, 6)

The code above creates two maps, map1 and map2, and then uses the zip method to create a new iterator of pairs from the two maps. Finally, the code iterates over the pairs and prints them out.

Parts of the code:

  • let map1 = [1, 2, 3];: creates a map with the values 1, 2, and 3.
  • let map2 = [4, 5, 6];: creates a map with the values 4, 5, and 6.
  • let zipped_map = map1.iter().zip(map2.iter());: creates a new iterator of pairs from the two maps.
  • for pair in zipped_map {: iterates over the pairs.
  • println!("{:?}", pair);: prints out the pairs.
