How to Convert a Vector of Integers to a Vector of Strings in Rust - Step by Step Examples

How to Convert a Vector of Integers to a Vector of Strings in Rust ?

Answer

To convert a vector of integers to a vector of strings in Rust, you can use the `map()` method with the `to_string()` function.


✐ Examples

1 Convert Vector of Integers to Vector of Strings

In this example,

  1. We create a vector of integers named int_vector.
  2. We use the map() method with the to_string() function to convert each integer in int_vector to a string.

Rust Program

let int_vector = vec![1, 2, 3, 4, 5];
let str_vector: Vec<String> = int_vector.iter().map(|&x| x.to_string()).collect();
println!("{:?}", str_vector);

Output

["1", "2", "3", "4", "5"]

Summary

In this tutorial, we learned How to Convert a Vector of Integers to a Vector of Strings in Rust language with well detailed examples.
