# Trait std::cmp::PartialOrd 1.0.0 [−] [src]

    #[lang = "ord"]
    pub trait PartialOrd<Rhs = Self>: PartialEq<Rhs> where
        Rhs: ?Sized, {
        fn partial_cmp(&self, other: &Rhs) -> Option<Ordering>;

        fn lt(&self, other: &Rhs) -> bool { ... }
        fn le(&self, other: &Rhs) -> bool { ... }
        fn gt(&self, other: &Rhs) -> bool { ... }
        fn ge(&self, other: &Rhs) -> bool { ... }
    }

Trait for values that can be compared for a sort-order.

The comparison must satisfy, for all `a`, `b` and `c`:

- antisymmetry: if `a < b` then `!(a > b)`, as well as `a > b` implying `!(a < b)`; and
- transitivity: `a < b` and `b < c` implies `a < c`. The same must hold for both `==` and `>`.

Note that these requirements mean that the trait itself must be implemented symmetrically and transitively: if `T: PartialOrd<U>` and `U: PartialOrd<V>` then `U: PartialOrd<T>` and `T: PartialOrd<V>`.

## 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 declaration order.

## How can I implement `PartialOrd`?

`PartialOrd` only requires implementation of the `partial_cmp` method, with the others generated from default implementations.

However it remains possible to implement the others separately for types which do not have a total order. For example, for floating point numbers, `NaN < 0 == false` and `NaN >= 0 == false` (cf. IEEE 754-2008 section 5.11).

`PartialOrd` requires your type to be `PartialEq`.

Implementations of `PartialEq`, `PartialOrd`, and `Ord` must agree with each other. It's easy to accidentally make them disagree by deriving some of the traits and manually implementing others.

If your type is `Ord`, you can implement `partial_cmp()` by using `cmp()`:

    use std::cmp::Ordering;

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

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

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

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

You may also find it useful to use `partial_cmp()` on your type's fields. Here is an example of `Person` types who have a floating-point `height` field that is the only field to be used for sorting:

    use std::cmp::Ordering;

    struct Person {
        id: u32,
        name: String,
        height: f64,
    }

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

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

# Examples

    let x : u32 = 0;
    let y : u32 = 1;

    assert_eq!(x < y, true);
    assert_eq!(x.lt(&y), true);Run

## Required Methods

### `fn partial_cmp(&self, other: &Rhs) -> Option<Ordering>`

This method returns an ordering between `self` and `other` values if one exists.

# Examples

    use std::cmp::Ordering;

    let result = 1.0.partial_cmp(&2.0);
    assert_eq!(result, Some(Ordering::Less));

    let result = 1.0.partial_cmp(&1.0);
    assert_eq!(result, Some(Ordering::Equal));

    let result = 2.0.partial_cmp(&1.0);
    assert_eq!(result, Some(Ordering::Greater));Run

When comparison is impossible:

    let result = std::f64::NAN.partial_cmp(&1.0);
    assert_eq!(result, None);Run

## Provided Methods

### `fn lt(&self, other: &Rhs) -> bool`

This method tests less than (for `self` and `other`) and is used by the `<` operator.

# Examples

    let result = 1.0 < 2.0;
    assert_eq!(result, true);

    let result = 2.0 < 1.0;
    assert_eq!(result, false);Run

### `fn le(&self, other: &Rhs) -> bool`

This method tests less than or equal to (for `self` and `other`) and is used by the `<=` operator.

# Examples

    let result = 1.0 <= 2.0;
    assert_eq!(result, true);

    let result = 2.0 <= 2.0;
    assert_eq!(result, true);Run

### `fn gt(&self, other: &Rhs) -> bool`

This method tests greater than (for `self` and `other`) and is used by the `>` operator.

# Examples

    let result = 1.0 > 2.0;
    assert_eq!(result, false);

    let result = 2.0 > 2.0;
    assert_eq!(result, false);Run

### `fn ge(&self, other: &Rhs) -> bool`

This method tests greater than or equal to (for `self` and `other`) and is used by the `>=` operator.

# Examples

    let result = 2.0 >= 1.0;
    assert_eq!(result, true);

    let result = 2.0 >= 2.0;
    assert_eq!(result, true);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`)
