<small>There is a new edition of the book and this is an old link.</small>
> Rust does not allow you to create your own operators or overload arbitrary operators, but the operations and corresponding traits listed in `std::ops` can be overloaded by implementing the traits associated with the operator.
```rust
use std::ops::Add;
#[derive(Debug,PartialEq)]
struct Point {
x: i32,
y: i32,
}
impl Add for Point {
type Output = Point;
fn add(self, other: Point) -> Point {
Point {
x: self.x + other.x,
y: self.y + other.y,
}
}
}
fn main() {
assert_eq!(Point { x: 1, y: 0 } + Point { x: 2, y: 3 },
Point { x: 3, y: 3 });
}
```
