1.8.0[−][src]Trait nom::lib::std::ops::AddAssign
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, 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.
