Types

type Node

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

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

func NewNode

func NewNode(node int64, epoch int64, nodeBits, stepBits uint8) (*Node, error)

NewNode returns a new snowflake node that can be used to generate snowflake IDs

func (*Node) Generate

func (n *Node) Generate() int64

Generate creates and returns a unique snowflake ID To help guarantee uniqueness - Make sure your system is keeping accurate system time - Make sure you never have multiple nodes running with the same node ID

func (*Node) GenerateBatch

func (n *Node) GenerateBatch(c uint16) []int64

GenerateBatch creates and returns a batch of unique snowflake ID To help guarantee uniqueness - Make sure your system is keeping accurate system time - Make sure you never have multiple nodes running with the same node ID
