Module tracing_core::stdlib::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.

Structs

• Reverse
  A helper struct for reverse ordering.

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.
• max_by_key
  Returns the element that gives the maximum value from the specified function.
• min
  Compares and returns the minimum of two values.
• min_by
  Returns the minimum of two values with respect to the specified comparison function.
• min_by_key
  Returns the element that gives the minimum value from the specified function.
• minmaxExperimental
  Compares and sorts two values, returning minimum and maximum.
• minmax_byExperimental
  Returns minimum and maximum values with respect to the specified comparison function.
• minmax_by_keyExperimental
  Returns minimum and maximum values with respect to the specified key function.

Derive Macros

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