type SplitMix64 struct {
	// contains filtered or unexported fields
}

SplitMix64 hold the state required by the SplitMix64 generator.

func (*SplitMix64) Int63

func (x *SplitMix64) Int63() int64

Int63 returns a non-negative pseudo-random 63-bit integer as an int64.

func (*SplitMix64) Seed

func (x *SplitMix64) Seed(seed int64)

Seed seed SplitMix64 random number generator with the given value.

func (*SplitMix64) Uint64

func (x *SplitMix64) Uint64() uint64

Uint64 returns the next pseudo random number generated, before start you must provvide one 64 unsigned bit seed.
