Below code does not help developers in case of an error with the size set using generic type parameter:
contour_points.push(Point::new(cast(pos3.x).unwrap(), cast(pos3.y).unwrap()));To help developers understand the error easily, code is updated with the error message like below:
contour_points.push(Point::new( cast(pos3.x).expect("Generic Type Parameter T should be bigger than width."), cast(pos3.y).expect("Generic Type Parameter T should be bigger than height."), ));
