Trait std::ops::AddAssign 1.8.0[−][src]
pub trait AddAssign<Rhs = Self> {
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 });Run

fn add_assign(&mut self, rhs: Rhs)
[src]Implementors
Implements the += operator for appending to a String.
This has the same behavior as the push_str method.
