UUID package for Go language

This package provides pure Go implementation of Universally Unique Identifier (UUID). Supported both creation and parsing of UUIDs.

With 100% test coverage and benchmarks out of box.

Supported versions:

• Version 1, based on timestamp and MAC address (RFC 4122)
• Version 2, based on timestamp, MAC address and POSIX UID/GID (DCE 1.1)
• Version 3, based on MD5 hashing (RFC 4122)
• Version 4, based on random numbers (RFC 4122)
• Version 5, based on SHA-1 hashing (RFC 4122)

Installation

Use the go command:

$ go get github.com/satori/go.uuid

Requirements

UUID package tested against Go >= 1.6.

Example

package main

import (
    "fmt"
    "github.com/satori/go.uuid"
)

func main() {
    // Creating UUID Version 4
    // panic on error
    u1 := uuid.Must(uuid.NewV4())
    fmt.Printf("UUIDv4: %s\n", u1)

    // or error handling
    u2, err := uuid.NewV4()
    if err != nil {
        fmt.Printf("Something went wrong: %s", err)
        return
    }
    fmt.Printf("UUIDv4: %s\n", u2)

    // Parsing UUID from string input
    u2, err := uuid.FromString("6ba7b810-9dad-11d1-80b4-00c04fd430c8")
    if err != nil {
        fmt.Printf("Something went wrong: %s", err)
        return
    }
    fmt.Printf("Successfully parsed: %s", u2)
}
