Trait steed::ops::MulAssign1.8.0 [−] [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;
}

Required Methods
