Trait nom::lib::std::ops::Add

#[lang = "add"]
pub trait Add<RHS = Self> {
    type Output;
    
#[must_use]
fn add(self, rhs: RHS) -> Self::Output;
}

The addition operator +.

Note that RHS is Self by default, but this is not mandatory. For example, std::time::SystemTime implements Add<Duration>, which permits operations of the form SystemTime = SystemTime + Duration.

Examples

Addable points

use std::ops::Add;

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

impl Add for Point {
    type Output = Point;

    fn add(self, other: Point) -> Point {
        Point {
            x: self.x + other.x,
            y: self.y + other.y,
        }
    }
}

assert_eq!(Point { x: 1, y: 0 } + Point { x: 2, y: 3 },
           Point { x: 3, y: 3 });

Implementing Add with generics

Here is an example of the same Point struct implementing the Add trait using generics.

use std::ops::Add;

#[derive(Debug, PartialEq)]
struct Point<T> {
    x: T,
    y: T,
}

// Notice that the implementation uses the associated type `Output`.
impl<T: Add<Output=T>> Add for Point<T> {
    type Output = Point<T>;

    fn add(self, other: Point<T>) -> Point<T> {
        Point {
            x: self.x + other.x,
            y: self.y + other.y,
        }
    }
}

assert_eq!(Point { x: 1, y: 0 } + Point { x: 2, y: 3 },
           Point { x: 3, y: 3 });

Associated Types

type Output

The resulting type after applying the + operator.

Required Methods

#[must_use]

fn add(self, rhs: RHS) -> Self::Output

Performs the + operation.
