a 4-byte value representing the seconds since the Unix epoch,

a 3-byte machine identifier,

a 2-byte process id, and

a 3-byte counter, starting with a random value.

Installation

Use the go command:

go get github.com/nobugtodebug/go-objectid

Example

package main

import (
	"fmt"
	"github.com/nobugtodebug/go-objectid"
)

func main() {
	objid := objectid.New()
	fmt.Printf("ObjectId: %s\n", objid)
	objid = objectid.Parse("55cc60946f29581a606930aa")
	fmt.Printf("%d-%d-%d-%d\n", objid.Timestamp(), objid.Machine(), objid.Pid(), objid.Increment())
}
