Functions

func New

func New(seed int64) (uuid.UUID, error)

New returns a Random (Version 4) UUID.

Copied from the github.com/google/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.
