trait Mul<T>

The multiplication operator *.

a * b on a type with a Mul instance calls mul(a, b). int and float have builtin instances. On Matrix values * is matrix multiplication.

Examples#

use tests::assert;
class V2 {
    pub x: int,
    pub y: int,
}

impl Mul for V2 {
    pub fn mul(V2 a, V2 b) -> V2 {
        return new V2(a.x * b.x, a.y * b.y);
    }
}

fn main() {
    let p = new V2(2, 3) * new V2(4, 5);
    assert!(p.x == 8);
    assert!(p.y == 15);
}
