core::ops::AddAssign - Rust
Description: API documentation for the Rust `AddAssign` trait in crate `core`.
Keywords: rust, rustlang, rust-lang, AddAssign

# 1.8.0[−][src]Trait core::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 });
