Trait nom::lib::std::prelude::v1::v1::Ord

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

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

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 derived on structs, it will produce a lexicographic ordering based on the top-to-bottom declaration order of the struct’s members. When derived on enums, variants are ordered by their top-to-bottom discriminant order.

Lexicographical comparison

Lexicographical comparison is an operation with the following properties:

• Two sequences are compared element by element.
• The first mismatching element defines which sequence is lexicographically less or greater than the other.
• If one sequence is a prefix of another, the shorter sequence is lexicographically less than the other.
• If two sequence have equivalent elements and are of the same length, then the sequences are lexicographically equal.
• An empty sequence is lexicographically less than any non-empty sequence.
• Two empty sequences are lexicographically equal.

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]

pub 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]

pub fn max(self, other: Self) -> Self

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));

#[must_use]

pub fn min(self, other: Self) -> Self

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));

#[must_use]

pub fn clamp(self, min: Self, max: Self) -> Self

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

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

impl Ord for str

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.
