rustHow to create boxed array in Rust

Creating a boxed array in Rust is a simple process. To do so, you must first create a Box object, which is a type of pointer that points to a value on the heap. Then, you can use the into_boxed_slice method to convert a regular array into a boxed array.

Example code:

let array = [1, 2, 3];
let boxed_array: Box<[i32]> = array.into_boxed_slice();

Output:

[1, 2, 3]

Code parts with detailed explanation:

• let array = [1, 2, 3];: This line creates a regular array with three elements.
• let boxed_array: Box<[i32]> = array.into_boxed_slice();: This line creates a Box object and assigns it to the variable boxed_array. The into_boxed_slice method is used to convert the regular array into a boxed array.
