Module std::cmp

Functionality for ordering and comparison.

This module defines both PartialOrd and PartialEq traits which are used by the compiler to implement comparison operators. Rust programs may implement PartialOrd to overload the <, <=, >, and >= operators, and may implement PartialEq to overload the == and != operators.

Examples

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

// these two lines are equivalent
assert_eq!(x < y, true);
assert_eq!(x.lt(&y), true);

// these two lines are also equivalent
assert_eq!(x == y, false);
assert_eq!(x.eq(&y), false);

Enums

Ordering

An Ordering is the result of a comparison between two values.

Traits

Eq

Trait for equality comparisons which are equivalence relations.

Ord

Trait for types that form a total order.

PartialEq

Trait for equality comparisons which are partial equivalence relations.

PartialOrd

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

Functions

max

Compare and return the maximum of two values.

min
