Trait redox::ops::AddAssign [−] [src]

pub trait AddAssign<Rhs = Self> {
    fn add_assign(&mut self, Rhs);
}
Unstable (op_assign_traits)

: recently added

The AddAssign trait is used to specify the functionality of +=.

Examples

A trivial implementation of AddAssign. When Foo += Foo happens, it ends up calling add_assign, and therefore, main prints Adding!.

#![feature(augmented_assignments)]
#![feature(op_assign_traits)]

use std::ops::AddAssign;

#[derive(Copy, Clone)]
struct Foo;

impl AddAssign for Foo {
    fn add_assign(&mut self, _rhs: Foo) {
        println!("Adding!");
    }
}

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