type UUID 

type UUID [16]byte

A UUID is a 128 bit (16 byte) Universal Unique IDentifier as defined in RFC 4122.

Must returns uuid if err is nil and panics otherwise.

func NewHash 

func NewHash(h hash.Hash, space UUID, data []byte, version int) UUID

NewHash returns a new UUID derived from the hash of space concatenated with data generated by h. The hash should be at least 16 byte in length. The first 16 bytes of the hash are used to form the UUID. The version of the UUID will be the lower 4 bits of version.

func NewMD5 

func NewMD5(space UUID, data []byte) UUID

NewMD5 returns a new MD5 (Version 3) UUID based on the supplied name space and data. It is the same as calling: 

NewHash(md5.New(), space, data, 3)

func NewRandom 

func NewRandom() (UUID, error)

NewRandom returns a Random (Version 4) UUID.

The strength of the UUIDs is based on the strength of the crypto/rand package.

A note about uniqueness derived from the UUID Wikipedia entry: 

Randomly generated UUIDs have 122 random bits.  One's annual risk of being
hit by a meteorite is estimated to be one chance in 17 billion, that
means the probability is about 0.00000000006 (6 × 10−11),
equivalent to the odds of creating a few tens of trillions of UUIDs in a
year and having one duplicate.

func NewSHA1 

func NewSHA1(space UUID, data []byte) UUID

NewSHA1 returns a new SHA1 (Version 5) UUID based on the supplied name space and data. It is the same as calling: 

NewHash(sha1.New(), space, data, 5)

func (UUID) Bytes 

func (uuid UUID) Bytes() []byte

Bytes returns bytes slice representation of UUID.

func (UUID) String 

func (uuid UUID) String() string

String returns the string form of uuid, xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx , or "" if uuid is invalid.
