rustHow to replace box value in Rust

Replacing a box value in Rust is a simple process. To do this, you must first create a new box with the desired value, then assign the new box to the old box. This is demonstrated in the following example:

let mut old_box = Box::new(5);
let new_box = Box::new(10);
old_box = new_box;

The output of this code will be:

()

The code consists of three parts:

1. let mut old_box = Box::new(5); - This creates a new box with the value 5.
2. let new_box = Box::new(10); - This creates a new box with the value 10.
3. old_box = new_box; - This assigns the new box to the old box, replacing the old value with the new one.
