Overview

Package utils provides common utility functions.

Provided functionalities: - sorting - comparators

Index

• func IntComparator(a, b interface{}) int
• func Sort(values []interface{}, comparator Comparator)
• func StringComparator(a, b interface{}) int
• type Comparator

Functions

func IntComparator

func IntComparator(a, b interface{}) int

IntComparator provides a basic comparison on ints

func Sort

func Sort(values []interface{}, comparator Comparator)

Sort sorts values (in-place) with respect to the given comparator.

Uses Go's sort (hybrid of quicksort for large and then insertion sort for smaller slices).

func StringComparator

func StringComparator(a, b interface{}) int

StringComparator provides a fast comparison on strings

Types

type Comparator

type Comparator func(a, b interface{}) int

Comparator will make type assertion (see IntComparator for example), which will panic if a or b are not of the asserted type.

Should return a number:

negative , if a < b
zero     , if a == b
positive , if a > b
