Rust: How do you implement operator overloading?

1use std::ops::Add;
2
3struct Point { x: f64, y: f64 }
4
5impl Add for Point {
6    type Output = Point;
7
8    fn add(self, other: Point) -> Point {
9        Point {
10            x: self.x + other.x,
11            y: self.y + other.y,
12        }
13    }
14}
15
16let p1 = Point { x: 1.0, y: 2.0 };
17let p2 = Point { x: 3.0, y: 4.0 };
18let p3 = p1 + p2;

1use std::ops::Index;

3struct Matrix {
4    data: Vec<Vec<f64>>,
5}
6
7impl Index<usize> for Matrix {
8    type Output = Vec<f64>;
9
10    fn index(&self, row: usize) -> &Vec<f64> {
11        &self.data[row]
12    }
13}
