rustHow to map an array in Rust

Mapping an array in Rust is a simple process. It involves using the map method on an array to apply a function to each element of the array.

let arr = [1, 2, 3];
let mapped_arr = arr.map(|x| x * 2);

The output of the above code will be [2, 4, 6].

Code explanation

• let arr = [1, 2, 3]: This creates an array with the elements 1, 2, and 3.
• let mapped_arr = arr.map(|x| x * 2): This uses the map method to apply the function x * 2 to each element of the arr array.
• [2, 4, 6]: This is the output of the code, which is an array with the elements 2, 4, and 6.
