结构体

1. struct Point {
2. x int
3. y int
4. }

6. p := Point{
7. x: 10
8. y: 20
9. }
10. println(p.x) // Struct fields are accessed using a dot

上面的结构体都在栈上分配。如果需要在堆上分布，需要用取地址的&操作符：

1. pointer := &Point{10, 10}  // Alternative initialization syntax for structs with 3 fields or fewer
2. println(pointer.x) // Pointers have the same syntax for accessing fields

V语言不支持子类继承，但是可以嵌入匿名结构体成员：

1. // TODO: this will be implemented later in June
2. struct Button {
3. Widget
4. title string
5. }

7. button := new_button('Click me')
8. button.set_pos(x, y)

10. // Without embedding we'd have to do
11. button.widget.set_pos(x,y)
