How to Convert an Array of Integers to an Array of Strings in Rust - Step by Step Examples

How to Convert an Array of Integers to an Array of Strings in Rust ?

Answer

To convert an array of integers to an array of strings in Rust, you can use the map function with the to_string method to convert each integer to a string.


✐ Examples

1 Convert Array of Integers to Array of Strings

In this example,

  1. Create an array of integers.
  2. Use the map function with the to_string method to convert each integer to a string and store it in a new array of strings.

Rust Program

fn main() {
    let int_array = [1, 2, 3, 4, 5];
    let string_array: Vec<String> = int_array.iter().map(|&x| x.to_string()).collect();

    for string in string_array {
        println!("{}", string);
    }
}

Output

1
2
3
4
5

Summary
