rust vec to array

To convert a Rust Vec to an array, you can use the into_boxed_slice method followed by the into method. Here's an example:

fn main() {
    let vec = vec![1, 2, 3, 4, 5];
    let array: Box<[i32]> = vec.into_boxed_slice().into();
    println!("{:?}", array);
}

In this example, we first create a Vec called vec with some elements. Then, we call the into_boxed_slice method on the Vec to convert it into a boxed slice. Finally, we call the into method on the boxed slice to convert it into an array. The resulting array is then printed using println!.

Please note that the size of the array needs to be known at compile-time. If the size is dynamic or unknown, you may need to use a Vec instead.

I hope this helps! Let me know if you have any further questions.
