Function SetRand

uuid.go:319–325

SetRand sets the random number generator to r, which implements io.Reader. If r.Read returns an error when the package requests random data then a panic will be issued. Calling SetRand with nil sets the random number generator to the default generator.

(r io.Reader)

// Calling SetRand with nil sets the random number generator to the default
// generator.
func SetRand(r io.Reader) {
	if r == nil {
		rander = rand.Reader
		return
	}
	rander = r
}
