UUID (Universally Unique Identifier) is a simple package that implements V4 of the UUID specification.
It also aims to make very basic assumptions of how a empty UUID behaves when used for verifying and checking for equality.
There are few methods for creating a UUID, with or without a random, because
there are some environments that can not depend on the basic global random in
the standard library. Locking when generating a lot of ids can cause various
issues and identify themselves when using -race.
id, err := uuid.New()
if err != nil {
panic(err)
}
fmt.Println(id.String())
