# Module tetcore_std::cmp 1.0.0[−][src]

## Expand description

Functionality for ordering and comparison.

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

`Eq`

and`PartialEq`

are traits that allow you to define total and partial equality between values, respectively. Implementing them overloads the`==`

and`!=`

operators.`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.`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.

## Macros

Eq | Derive macro generating an impl of the trait |

Ord | Derive macro generating an impl of the trait |

PartialEq | Derive macro generating an impl of the trait |

PartialOrd | Derive macro generating an impl of the trait |

## Structs

Reverse | A helper struct for reverse ordering. |

## Enums

Ordering | An |

## 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 | 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. |
