go-uuid

A package providing UUID v1, v4 and Ordered UUID with utility interface and fonction

What is an OrderedUUID ?

It's an UUID v1 where the timestamp part of the uuid is move in the begening of the UUID. It's mostly useful when you use them as a primary key or an index in a database like MySQL as the index we now be sorted and all new element should be added on top of the index.

Utility function?

Yes, the UUID struct has the Scan/Value function that follow the driver.Valuer / driver.Scanner interface. This let you scan your struct with an UUID right from the database! It also add implement the encoding.TextUnmarshaler and the encoding.TextMarshaler for encoding/decoding.

Following UUID formats for decoding are supported:

   "6ba7b810-9dad-11d1-80b4-00c04fd430c8",
   "6ba7b8109dad11d180b400c04fd430c8"

Supported UUID text representation follows:

   uuid := canonical | hashlike
   plain := canonical | hashlike
   canonical := 4hexoct '-' 2hexoct '-' 2hexoct '-' 6hexoct
   hashlike := 12hexoct
