How to implement Add trait for custom types

Implement the Add trait for your custom type by defining the add method inside an impl block that specifies the trait and the return type.

use std::ops::Add;

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,
        }
    }
}

In Simple Terms: This tells Rust how to use the plus sign (+) with your custom data type, just like it knows how to add numbers. It matters because it lets you write natural math-like code for your own objects instead of calling a specific function every time. Think of it as teaching the language a new rule for combining your specific items.
