Package rand provides utilities related to randomization.
Int returns a non-negative pseudo-random int.
IntnRange generates an int64 integer in range [min,max). By design this should panic if input is invalid, <= 0.
Intn generates an integer in range [0,max). By design this should panic if input is invalid, <= 0.
IntnRange generates an integer in range [min,max). By design this should panic if input is invalid, <= 0.
Perm returns, as a slice of n ints, a pseudo-random permutation of the integers [0,n) from the default Source.
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.
Seed seeds the rng with the provided seed.
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)
