Functions

func ID

func ID() string

func IDInt64

func IDInt64() int64

func ServerId

func ServerId(snowId string) int64

ServerId 根据生成的snowId计算出机器ID

Types

type Node

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

A Node struct holds the basic information needed for a snowflake generator

func NewNode

func NewNode(node int64) (*Node, error)

NewNode returns a new snowflake node that can be used to generate snowflake IDs 参数为机器ID 机器注册中心ID

func (*Node) NextIdInt64

func (n *Node) NextIdInt64() int64

NextIdInt64 返回ID的int64形式

func (*Node) NextIdStr

func (n *Node) NextIdStr() string

NextIdStr 返回ID的字符串形式
