Types

type Nano

type Nano struct {
	Alphabet string
	Size     int
}

func DefaultNano

func DefaultNano() *Nano

func (*Nano) Generate

func (nano *Nano) Generate() (string, error)

Generate is a low-level function to change alphabet and ID size.

func (*Nano) Must

func (nano *Nano) Must(l ...int) string

Must is the same as New but panics on error.

func (*Nano) MustGenerate

func (nano *Nano) MustGenerate() string

MustGenerate is the same as Generate but panics on error.

func (*Nano) New

func (nano *Nano) New(l ...int) (string, error)

New generates secure URL-friendly unique ID. Accepts optional parameter - length of the ID to be generated (21 by default).

type UUID

type UUID [16]byte

UUID type.

func (UUID) Hex

func (this UUID) Hex() string

Hex returns a hex string representation of the UUID in xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx format.

func (UUID) String

func (this UUID) String() string

type Worker

type Worker struct {
	// contains filtered or unexported fields
}

定义一个woker工作节点所需要的基本参数

var Snowflake *Worker

func NewWorker

func NewWorker(workerId int64) (*Worker, error)

实例化一个工作节点 workerId 为当前节点的id

func RandomWorker

func RandomWorker() *Worker

func (*Worker) ConvToShort62

func (w *Worker) ConvToShort62(id int64) (output string)

func (*Worker) GetId

func (w *Worker) GetId() int64

生成方法一定要挂载在某个woker下，这样逻辑会比较清晰 指定某个节点生成id

func (*Worker) GetString

func (w *Worker) GetString() string

func (*Worker) GetStringHex

func (w *Worker) GetStringHex() string

func (*Worker) GetStringHexTrim

func (w *Worker) GetStringHexTrim() string

func (*Worker) Short62

func (w *Worker) Short62() (output string)

func (*Worker) WorkerId

func (w *Worker) WorkerId() int64
