# Trait bitflags::__core::ops::MulAssign [−] [src]

    pub trait MulAssign<Rhs = Self> {
        fn mul_assign(&mut self, Rhs);
    }

The `MulAssign` trait is used to specify the functionality of `*=`.

# Examples

A trivial implementation of `MulAssign`. When `Foo *= Foo` happens, it ends up calling `mul_assign`, and therefore, `main` prints `Multiplying!`.

    use std::ops::MulAssign;

    struct Foo;

    impl MulAssign for Foo {
        fn mul_assign(&mut self, _rhs: Foo) {
            println!("Multiplying!");
        }
    }

    fn main() {
        let mut foo = Foo;
        foo *= Foo;
    }

## 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`)
