AddAssign in core::ops - Rust
Description: The addition assignment operator `+=`.

# Trait AddAssign

1.8.0 · Source

    pub trait AddAssign<Rhs = Self> {
        // Required method
        fn add_assign(&mut self, rhs: Rhs);
    }

Expand description

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);
