[Rust] The constructor of Point class

impl Point {
    // Constructor, which is just a regular method
    pub fn new(x: f64, y: f64) -> Point {
        let mut p = Point{ x: 0.0, y: 0.0 };

        // Set the fields of Point through setters
        p.set_x(x);
        p.set_y(y);

        p
    }
}
