Using Data in Functions

Data modules can be passed to and returned from functions, enabling you to manipulate them easily.

Example: Passing Data to Functions

def print_point(Point p):
    print($"Point(x: {p.x}, y: {p.y})");

def main():
    Point p = Point(3, 4);
    print_point(p); // Outputs: Point(x: 3, y: 4)

Example: Returning Data from Functions

def create_point(int x, int y) -> Point:
    return Point(x, y);

def main():
    Point p = create_point(5, 7);
    print($"Created Point: x={p.x}, y={p.y}");

By using functions with data, you can create and manipulate complex structures easily.

Conclusion

Data modules are the foundation of Flint’s design, allowing you to create, structure, and manage information effectively. From default values to nested structures, they provide a flexible yet powerful way to organize your program’s core logic. You’ve taken your first step into Flint’s data-centric world—congratulations!
