rand.go

func Int Uses

func Int() int

Int returns a non-negative pseudo-random int.

func Int63nRange Uses

func Int63nRange(min, max int64) int64

IntnRange generates an int64 integer in range [min,max). By design this should panic if input is invalid, <= 0.

func Intn Uses

func Intn(max int) int

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

func IntnRange Uses

func IntnRange(min, max int) int

IntnRange generates an integer in range [min,max). By design this should panic if input is invalid, <= 0.

func Perm Uses

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 SafeEncodeString Uses

func SafeEncodeString(s string) string

SafeEncodeString encodes s using the same characters as rand.String. This reduces the chances of bad words and ensures that strings generated from hash functions appear consistent throughout the API.

func Seed Uses

func Seed(seed int64)

Seed seeds the rng with the provided seed.

func String Uses

func String(n int) string

String generates a random alphanumeric string, without vowels, which is n characters long. This will panic if n is less than zero. How the random string is created: - we generate random int63's - from each int63, we are extracting multiple random letters by bit-shifting and masking - if some index is out of range of alphanums we neglect it (unlikely to happen multiple times in a row)
