Thank you @bravegnu

I was trying to create a template then i found we may not be able to use move function name since move is a keyword in rust.

fn main() {
    start();
    repeat(3) {
        move();
    }
    stop();
}

We can use karel_move()

fn main() {
    start();
    repeat(3) {
        karel_move();
    }
    stop();
}
