Functions ¶

func Intn ¶

func Intn(max int) int

Intn generates an integer in range 0->max. By design this should panic if input is invalid, <= 0.

func Perm ¶

func Perm(n int) []int

Perm returns, as a slice of n ints, a pseudo-random permutation of the integers [0,n) from the default Source.

func Seed ¶

func Seed(seed int64)

Seed seeds the rng with the provided seed.

func Shuffle ¶

func Shuffle(data Shufflable)

func String ¶

func String(length int) string

String generates a random alphanumeric string n characters long. This will panic if n is less than zero.

Types ¶

type Shufflable ¶

type Shufflable interface {
	Len() int
	Swap(i, j int)
}

A type that satisfies the rand.Shufflable interface can be shuffled by Shuffle. Any sort.Interface will satisfy this interface.
