Rust Programming Cookbook

How to do it...

The steps for this recipe are as follows:

1. Use cargo to create a new project, cargo new sequences --lib, or clone it from this book's GitHub repository (https://github.com/PacktPublishing/Rust-Programming-Cookbook). Use Visual Studio Code and Terminal to open the project's directory.
2. With the test module ready, let's start with arrays. Arrays in Rust have a familiar syntax but they follow a stricter definition. We can try out various abilities of the Rust array in a test:

    #[test]    fn exploring_arrays() {        let mut arr: [usize; 3] = [0; 3];        assert_eq!(arr, [0, 0, 0]);        let arr2: [usize; 5] = [1,2,3,4,5];        assert_eq!(arr2, [1,2,3,4,5]);        arr[0] = 1;        assert_eq!(arr, [1, 0, 0]);        assert_eq!(arr[0], 1); assert_eq!(mem::size_of_val(&arr), ...
