# 1.8.0[−][src]Trait std::ops::MulAssign

    #[lang = "mul_assign"]pub trait MulAssign<Rhs = Self> {
        fn mul_assign(&mut self, rhs: Rhs);
    }

The multiplication assignment operator `*=`.

# Examples

    use std::ops::MulAssign;

    #[derive(Debug, PartialEq)]
    struct Frequency { hertz: f64 }

    impl MulAssign<f64> for Frequency {
        fn mul_assign(&mut self, rhs: f64) {
            self.hertz *= rhs;
        }
    }

    let mut frequency = Frequency { hertz: 50.0 };
    frequency *= 4.0;
    assert_eq!(Frequency { hertz: 200.0 }, frequency);
