struct Square { side: i32, } ```

Will expand to

```rust mod item; mod area; mod perimeter; mod scale; mod _CGQAQSUPERTRAIT__ { use std::ops::{Add, Sub, Mul, Div};

    fn area(&self) -> Self::Item;
    fn perimeter(&self) -> Self::Item;
    fn scale(&mut self, scale: Self::Item);
}

} use _CGQAQSUPERTRAIT__::Rect;

[doc = "Test this will keep after expand"]

[derive(Debug)]

struct Square { side: i32, } impl Rect for Square { type Item = crate::item::Item; fn area(&self) -> Self::Item { ::area(self) } fn perimeter(&self) -> Self::Item { ::perimeter(self) } fn scale(&mut self, scale: Self::Item) { ::scale(self, scale) } } ```
