func RandomSpec ¶

func RandomSpec(count uint, start, end int, letters, numbers bool, chars []rune) string

RandomSpec Creates a random string based on a variety of options, using supplied source of randomness.

If start and end are both 0, start and end are set to ' ' and 'z', the ASCII printable characters, will be used, unless letters and numbers are both false, in which case, start and end are set to 0 and math.MaxInt32.

If set is not nil, characters between start and end are chosen.

This method accepts a user-supplied rand.Rand instance to use as a source of randomness. By seeding a single rand.Rand instance with a fixed seed and using it for each call, the same random sequence of strings can be generated repeatedly and predictably.
