The `rand.Seed` method is currently deprecated, use rand Replace with the `NewSource` method. ``` // Deprecated: As of Go 1.20 there is no reason to call Seed with // a random value. Programs that call Seed with a known value to get // a specific sequence of results should use New(NewSource(seed)) to // obtain a local random generator. ``` --------- Signed-off-by: Young Xu <xuthus5@gmail.com> Co-authored-by: LinkinStars <linkinstar@foxmail.com>
