# 1.0.0[−][src]Trait std::ops::Sub

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

The subtraction operator `-`.

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

# Examples

## `Sub`tractable points

    use std::ops::Sub;

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

    impl Sub for Point {
        type Output = Point;

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

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

## Implementing `Sub` with generics

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

    use std::ops::Sub;

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

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

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

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

## Search Tricks

Prefix searches with a type followed by a colon (e.g., `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g., `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g., `str,u8` or `String,struct:Vec,test`)
