func New

func New(state [4]uint32) *Source

New create a new source.

func (*Source) Int63

func (s *Source) Int63() int64

Int63 implements math/rand.Source.

func (*Source) Seed

func (s *Source) Seed(seed int64)

Seed implements math/rand.Source.

func (*Source) SeedBySlice

func (s *Source) SeedBySlice(initKey []uint32)

SeedBySlice initializes the state by initKey.

func (*Source) Uint32

func (s *Source) Uint32() uint32

Uint32 returns pseudo-random uint32 values in the range [0, 1<<32).

func (*Source) Uint64

func (s *Source) Uint64() uint64

Uint64 implements math/rand.Source64
