In Mojo, composition is achieved by including one or more structs as fields within another struct, rather than using inheritance (which Mojo does not support). This is similar to how composition works in Go and Rust.

Example: Composition in Mojo Suppose you have two structs, Position and Drawable, and you want to compose them into a Sprite struct:

struct Position:
    var x: Int
    var y: Int

struct Drawable:
    fn draw(self):
        print("Drawing at position")

struct Sprite:
    var position: Position
    var drawable: Drawable

    fn render(self):
        self.drawable.draw()
        print(f"Sprite at ({self.position.x}, {self.position.y})")
