    Functions

    func Int

    func Int() int

      Int returns a non-negative pseudo-random int.

      func Int63nRange

      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

        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

          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

            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

              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

                func Seed(seed int64)

                  Seed seeds the rng with the provided seed.

                  func String

                  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)
