Functions ¶
func Int63nRange ¶
IntnRange generates an int64 integer in range [min,max). By design this should panic if input is invalid, <= 0.
func Intn ¶
Intn generates an integer in range [0,max). By design this should panic if input is invalid, <= 0.
func IntnRange ¶
IntnRange generates an integer in range [min,max). By design this should panic if input is invalid, <= 0.
func Perm ¶
Perm returns, as a slice of n ints, a pseudo-random permutation of the integers [0,n) from the default Source.
func SafeEncodeString ¶
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 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)
