# core::traits::Mul

The multiplication operator `*`.

## Signature

```rust theme={null}
pub trait Mul
```

## Examples

Multipliable types:

```rust theme={null}
assert!(3_u8 * 2_u8 == 6_u8);
```

Implementing `Mul` for a type:

```rust theme={null}
#[derive(Copy, Drop, PartialEq)]
struct Point {
    x: u32,
    y: u32,
}

impl PointMul of Mul {
    fn mul(lhs: Point, rhs: Point) -> Point {
        Point {
            x: lhs.x * rhs.x,
            y: lhs.y * rhs.y,
        }
    }
}

let p1 = Point { x: 2, y: 3 };
let p2 = Point { x: 1, y: 0 };
let p3 = p1 * p2;
assert!(p3 == Point { x: 2, y: 0 });
```
