func Float64() float64Float64 returns a float64 uniformly in [0, 1). Safe for concurrent callers.
func Hash(data []byte, seed uint64) uint64Hash returns a 64bit digest of the data with different ones for every seed.
func HashString(data string, seed uint64) uint64HashString returns a 64bit digest of the data with different ones for every seed.
func Int() intInt returns a random int. Safe for concurrent callers.
func Intn(n int) intIntn returns a int uniformly in [0, n). Safe for concurrent callers.
func Uint64() uint64Uint64 returns a random uint64. Safe for concurrent callers.
func Uint64n(n uint64) uint64Uint64n returns a uint64 uniformly in [0, n). Safe for concurrent callers.
type RNG uint64RNG is a random number generator. The zero value is valid.
func (r *RNG) Float64() (v float64)Float64 returns a float64 uniformly in [0, 1). Not safe for concurrent callers.
func (r *RNG) Int() intInt returns a random int. Not safe for concurrent callers.
func (r *RNG) Intn(n int) intIntn returns an int uniformly in [0, n). Not safe for concurrent callers.
func (r *RNG) Uint64() uint64Uint64 returns a random uint64. Not safe for concurrent callers.
func (r *RNG) Uint64n(n uint64) uint64Uint64n returns a uint64 uniformly in [0, n). Not safe for concurrent callers.
