rust loop vector by size

To create a Rust loop that iterates over a vector by size, you can use the iter() method along with the size() method of the vector. Here's an example:

fn main() {
    let vec = vec![1, 2, 3, 4, 5];

    for _ in vec.iter().take(vec.len()) {
        // Loop body
    }
}

In this example, the iter() method returns an iterator over the vector, and the size() method returns the size of the vector. The take() method is used to limit the number of iterations to the size of the vector.

Please note that the loop body is left empty in this example. You can add your desired logic inside the loop body.

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