# 1.8.0[−][src]Trait core::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);Run

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
