Module cmp 

Utilities for comparing and ordering values.

This module contains various tools for comparing and ordering values. In summary:

• PartialEq<Rhs> overloads the == and != operators. In cases where Rhs (the right hand side’s type) is Self, this trait corresponds to a partial equivalence relation.
• Eq indicates that the overloaded == operator corresponds to an equivalence relation.
• Ord and PartialOrd are traits that allow you to define total and partial orderings between values, respectively. Implementing them overloads the <, <=, >, and >= operators.
• Ordering is an enum returned by the main functions of Ord and PartialOrd, and describes an ordering of two values (less, equal, or greater).
• [Reverse] is a struct that allows you to easily reverse an ordering.
• max and min are functions that build off of Ord and allow you to find the maximum or minimum of two values.

For more details, see the respective documentation of each item in the list.

Enums

Ordering

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

Traits

Eq

Trait for comparisons corresponding to equivalence relations.

Ord

Trait for types that form a total order.

PartialEq

Trait for comparisons using the equality operator.

PartialOrd

Trait for types that form a partial order.

Functions

max

Compares and returns the maximum of two values.

max_by

Returns the maximum of two values with respect to the specified comparison function.

min

Compares and returns the minimum of two values.

Derive Macros

Eq

Derive macro generating an impl of the trait Eq.

PartialEq

Derive macro generating an impl of the trait PartialEq. The behavior of this macro is described in detail here.

PartialOrd

Derive macro generating an impl of the trait PartialOrd. The behavior of this macro is described in detail here.
