Functions

func RandomLowercaseStringWithLen

func RandomLowercaseStringWithLen(n int) string

RandomLowercaseStringWithLen returns a random string of specified length containing lowercase runes.

func RandomString

func RandomString() string

RandomString returns a random string with a predefined length of 12.

func RandomStringWithLen

func RandomStringWithLen(n int) string

RandomStringWithLen returns a random string of specified length containing upper- and lowercase runes.

func RandomStringWithPrefix

func RandomStringWithPrefix(prefix string, n int) string

RandomStringWithPrefix returns a random string of length n + len(prefix) with the given prefix, containing upper- and lowercase runes.

Types

type SafeRand

type SafeRand struct {
	// contains filtered or unexported fields
}

SafeRand is a concurrency-safe source of pseudo-random numbers. The Go stdlib's math/rand.Source is not concurrency-safe. The global source in math/rand would be concurrency safe (due to its internal use of lockedSource), but it is prone to inter-package interference with the PRNG state.
