rustHow to map a Rust slice?

Mapping a Rust slice is a way to apply a function to each element of a slice. This can be done using the map() method.

Example code

let numbers = [1, 2, 3, 4, 5];
let squares = numbers.map(|x| x * x);

Output example

[1, 4, 9, 16, 25]

Code explanation

• let numbers = [1, 2, 3, 4, 5];: This creates a slice of numbers.
• let squares = numbers.map(|x| x * x);: This uses the map() method to apply the function x * x to each element of the numbers slice.
