흔히 이렇게 알고 있다

Setting a failing random source causes uuid.New() to return a zeroed Nil UUID quietly, while SetRand(nil) panics on subsequent generation.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

컨트랙트

• uuid.SetRand with a failing entropy source causes uuid.New and uuid.NewString to panic immediately with the reader error while uuid.NewRandom returns uuid.Nil and the error, and uuid.SetRand(nil) safely restores crypto/rand without a nil pointer panic.
• uuid.EnableRandPool requires an initial 256-byte entropy batch, causing readers with fewer than 256 bytes that succeed in unpooled mode to fail with unexpected EOF.
• uuid.SetNodeID rejects byte slices shorter than 6 bytes and sets uuid.NodeInterface to user on valid slices.
• uuid.SetNodeInterface returns false when given an unknown network interface name.
• uuid.SetClockSequence masks the input integer to the lower 14 bits.
