Currently only Version 5 (SHA1) and Version 3 (MD5) are supported.

Functions

func FromInt

func FromInt(i *big.Int) (string, error)

FromInt creates a UUID from an integer.

DNS:  uuid.FromInt(0x6ba7b810_9dad_11d1_80b4_00c04fd430c8)

func MD5

func MD5(space string, data []byte) (string, error)

MD5 generates a version 3 UUID based on the supplied name space and data. Use SHA1 instead if you can.

func Parse

func Parse(s string) (string, error)

Parse decodes s into a UUID or returns an error. Both the standard UUID forms of xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx and urn:uuid:xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx are decoded as well as the Microsoft encoding {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx} and the raw hex encoding: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.

func SHA1

func SHA1(space string, data []byte) (string, error)

SHA1 generates a version 5 UUID based on the supplied name space and data.

func ToInt

func ToInt(x string) *big.Int

ToInt represents a UUID string as a 128-bit value.

func ToString

func ToString(x string) string

String represents a 128-bit UUID value as a string.

func URN

func URN(x string) (string, error)

URN reports the canonical URN of a UUID.

func Valid

func Valid(s string) error

Valid can be used to define a valid Valid.

func Variant

func Variant(x string) (int, error)

Variant reports the UUID variant.

func Version

func Version(x string) (int, error)

Version reports the UUID version.
