sortablebase64

Documentation

Overview

Package sortablebase64 contains routines for encoding text in a variant of base64. This variant has the useful property that encodings of numeric values retain their ordering under lexicographic (ASCII) sort as the values do under numeric sort.

Index

• Constants
• func DecUint64(s string) (string, error)
• func DecodeUint64(s string) (uint64, error)
• func EncodeUint64(n uint64) string
• func IncUint64(s string) (string, error)

Constants

const Alphabet = "0123456789=ABCDEFGHIJKLMNOPQRSTUVWXYZ_abcdefghijklmnopqrstuvwxyz"

Alphabet is an ordered list of characters used in sortablebase64 encoding. The order is drawn from the placement of these characters in the ASCII table.

Functions

func DecUint64

func DecUint64(s string) (string, error)

DecUint64 increments the sortablebase64-encoded uint64 s.

func DecodeUint64

func DecodeUint64(s string) (uint64, error)

DecodeUint64 returns a uint64 representing the sortablebase64-encoded string s, or an error.

func EncodeUint64

func EncodeUint64(n uint64) string

EncodeUint64 returns a string representing n in sortablebase64.

The returned string is always 11 bytes in length.

func IncUint64

func IncUint64(s string) (string, error)

IncUint64 increments the sortablebase64-encoded uint64 s.
