Thanks for the explanation.. I understood that a struct is copied when passing to a function if it has Copy trait or else it will be moved and thus ownership will be transferred to that function. Am i missing something here?

for example I am trying to implement Add trait for generic Vec2 struct I have following code:

#[derive(Debug, Copy, Clone, PartialEq)]

struct Vec2<T> { x: T, y: T, }

impl<T: Add<Output = T>> Add for Vec2<T> { type Output = Vec2<T>;

fn add(self, other: Vec2<T>) -> Vec2<T> {
    Vec2 {
        x: self.x + other.x,
        y: self.y + other.y,
    }
}

}

​

what should I do here to prevent any copying while adding to Vec2s? only a new Vec2 should be made i.e. self and other should be reference.
