Trait std::ops::SubAssign1.8.0[][src]

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

The subtraction assignment operator -=.


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

use std::ops::SubAssign;

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

impl SubAssign for Point {
    fn sub_assign(&mut self, other: Self) {
        *self = Self {
            x: self.x - other.x,
            y: self.y - other.y,

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

Required methods

pub fn sub_assign(&mut self, rhs: Rhs)[src]

Performs the -= operation.


let mut x: u32 = 12;
x -= 1;
assert_eq!(x, 11);
