# 1.0.0[−][src]Trait core::cmp::Ord

    pub trait Ord: Eq + PartialOrd<Self> {
    #[must_use]    fn cmp(&self, other: &Self) -> Ordering;

    #[must_use]    fn max(self, other: Self) -> Self
        where
            Self: Sized,
        { ... }
    #[must_use]    fn min(self, other: Self) -> Self
        where
            Self: Sized,

Trait for types that form a total order.

An order is a total order if it is (for all `a`, `b` and `c`):

- total and asymmetric: exactly one of `a < b`, `a == b` or `a > b` is true; and
- transitive, `a < b` and `b < c` implies `a < c`. The same must hold for both `==` and `>`.

## Derivable

This trait can be used with `#[derive]`. When `derive`d on structs, it will produce a lexicographic ordering based on the top-to-bottom declaration order of the struct's members. When `derive`d on enums, variants are ordered by their top-to-bottom discriminant order.

## How can I implement `Ord`?

`Ord` requires that the type also be `PartialOrd` and `Eq` (which requires `PartialEq`).

Then you must define an implementation for `cmp`. You may find it useful to use `cmp` on your type's fields.

Implementations of `PartialEq`, `PartialOrd`, and `Ord` must agree with each other. That is, `a.cmp(b) == Ordering::Equal` if and only if `a == b` and `Some(a.cmp(b)) == a.partial_cmp(b)` for all `a` and `b`. It's easy to accidentally make them disagree by deriving some of the traits and manually implementing others.

Here's an example where you want to sort people by height only, disregarding `id` and `name`:

    use std::cmp::Ordering;

    #[derive(Eq)]
    struct Person {
        id: u32,
        name: String,
        height: u32,
    }

    impl Ord for Person {
        fn cmp(&self, other: &Self) -> Ordering {
            self.height.cmp(&other.height)
        }
    }

    impl PartialOrd for Person {
        fn partial_cmp(&self, other: &Self) -> Option<Ordering> {
            Some(self.cmp(other))
        }
    }

    impl PartialEq for Person {
        fn eq(&self, other: &Self) -> bool {
            self.height == other.height
        }
    }

## Required methods

### `#[must_use]fn cmp(&self, other: &Self) -> Ordering`

This method returns an `Ordering` between `self` and `other`.

By convention, `self.cmp(&other)` returns the ordering matching the expression `self <operator> other` if true.

# Examples

    use std::cmp::Ordering;

    assert_eq!(5.cmp(&10), Ordering::Less);
    assert_eq!(10.cmp(&5), Ordering::Greater);
    assert_eq!(5.cmp(&5), Ordering::Equal);

## Provided methods

### `#[must_use]fn max(self, other: Self) -> Self where
Self: Sized,` 1.21.0

Compares and returns the maximum of two values.

Returns the second argument if the comparison determines them to be equal.

# Examples

    assert_eq!(2, 1.max(2));
    assert_eq!(2, 2.max(2));

Run

### `#[must_use]fn min(self, other: Self) -> Self where
Self: Sized,` 1.21.0

Compares and returns the minimum of two values.

Returns the first argument if the comparison determines them to be equal.

# Examples

    assert_eq!(1, 1.min(2));
    assert_eq!(2, 2.min(2));

Run

### `#[must_use]fn clamp(self, min: Self, max: Self) -> Self where
Self: Sized,`

🔬 This is a nightly-only experimental API. (`clamp` #44095)

Restrict a value to a certain interval.

Returns `max` if `self` is greater than `max`, and `min` if `self` is less than `min`. Otherwise this returns `self`.

# Panics

Panics if `min > max`.

# Examples

    #![feature(clamp)]

    assert!((-3).clamp(-2, 1) == -2);
    assert!(0.clamp(-2, 1) == 0);
    assert!(2.clamp(-2, 1) == 1);

Implements ordering of strings.

Strings are ordered lexicographically by their byte values. This orders Unicode code points based on their positions in the code charts. This is not necessarily the same as "alphabetical" order, which varies by language and locale. Sorting strings according to culturally-accepted standards requires locale-specific data that is outside the scope of the `str` type.
