std::ops::MulAssign

Trait std::ops::MulAssign

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

The multiplication assignment operator *=.

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;
}
