Should panic for invalid option values

[dolmen]

Do not silently ignore out of range values for options. Instead, panic.

yes, you are right. It has been fixed

[dolmen]

Well, validation should happen earlier, out of the Option function.

func BucketsCount(v int) Option {
	if v < 1 {
		panic("BucketsCount: value out of range")
	}
	return func(o *Options) {
		o.bucketsCount = v
	}
}

Sorry for being careless. You're so careful. Haha
