Predefined namespace UUID's

Types

type UUID

type UUID []byte

UUID contains UUID data

func UUID4

func UUID4() UUID

UUID4 generates random generated UUID v4

Example

fmt.Printf("UUID v4: %s\n", UUID4().String())

func UUID5

func UUID5(ns []byte, name string) UUID

UUID5 generates UUID v5 based on SHA-1 hash of namespace UUID and name

Example

fmt.Printf("UUID v5: %s\n", UUID5(NsURL, "http://www.domain.com").String())

func UUID7

func UUID7() UUID

UUID7 generates UUID v7 based on timestamp

Example

fmt.Printf("UUID v7: %s\n", UUID7().String())

func (UUID) IsZero

func (u UUID) IsZero() bool

IsZero returns true if UUID is empty

func (UUID) String

func (u UUID) String() string

String returns string representation of UUID
