Types

type Generator

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

Generator represents a UUID generator that generates UUIDs in sequence from a random starting point.

func NewGenerator

func NewGenerator() (*Generator, error)

NewGenerator returns a new Generator. It can fail if the crypto/rand read fails.

func (*Generator) Next

func (g *Generator) Next() [24]byte

Next returns the next UUID from the generator. Only the first 8 bytes can differ from the previous UUID, so taking a slice of the first 16 bytes is sufficient to provide a somewhat less secure 128 bit UUID.

It is OK to call this method concurrently.

func (*Generator) NextAsString

func (g *Generator) NextAsString() string

NextAsString returns the next UUID from the generator as a string.

type Service

type Service interface {
