Rust Array Literal

In Rust, an array literal is a way to initialize an array with a fixed number of elements. The syntax for creating an array literal in Rust is as follows:

let array_name = [element1, element2, element3, ...];

Here, array_name is the name of the array, and element1, element2, element3, etc., are the values of the elements in the array.

For example, if you want to create an array of integers with the values 1, 2, and 3, you can use the following array literal:

let my_array = [1, 2, 3];

You can access individual elements of the array using indexing. The index starts from 0, so to access the first element of the array, you would use my_array[0].

It's important to note that in Rust, arrays have a fixed size determined at compile-time. If you need a collection with a variable size, you should consider using a Vec (vector) instead.
