1.8.0[−][src]Trait sp_std::ops::AddAssign

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

The addition assignment operator +=.

Examples

This example creates a Point struct that implements the AddAssign trait, and then demonstrates add-assigning to a mutable Point.

use std::ops::AddAssign;

#[derive(Debug, Copy, Clone, PartialEq)]
struct Point {
    x: i32,
    y: i32,
}

impl AddAssign for Point {
    fn add_assign(&mut self, other: Self) {
        *self = Self {
            x: self.x + other.x,
            y: self.y + other.y,
        };
    }
}

let mut point = Point { x: 1, y: 0 };
point += Point { x: 2, y: 3 };
assert_eq!(point, Point { x: 3, y: 3 });

Required methods

fn add_assign(&mut self, rhs: Rhs)[−]

Performs the += operation.

Example

let mut x: u32 = 12;
x += 1;
assert_eq!(x, 13);
