Functions

func DeriveRand

func DeriveRand(r *rand.Rand) *rand.Rand

DeriveRand derives a new Rand deterministically from another random source. Unlike rand.New(rand.NewSource(seed)), the result is "more random" depending on the source and state of r.

NOTE: not crypto safe.

func RandIntBetween

func RandIntBetween(r *rand.Rand, min, max int) int

RandIntBetween returns a random int between two numbers inclusively.

func RandPositiveInt

func RandPositiveInt(r *rand.Rand, max sdk.Int) (sdk.Int, error)

RandPositiveInt get a rand positive sdk.Int

func RandStringOfLength

func RandStringOfLength(r *rand.Rand, n int) string

RandStringOfLength generates a random string of a particular length

func RandSubsetCoins

func RandSubsetCoins(r *rand.Rand, coins sdk.Coins) sdk.Coins

returns random subset of the provided coins will return at least one coin unless coins argument is empty or malformed i.e. 0 amt in coins

func RandTimestamp

func RandTimestamp(r *rand.Rand) time.Time

RandTimestamp generates a random timestamp

func RandomAmount

func RandomAmount(r *rand.Rand, max sdk.Int) sdk.Int

RandomAmount generates a random amount Note: The range of RandomAmount includes max, and is, in fact, biased to return max as well as 0.

func RandomDecAmount

func RandomDecAmount(r *rand.Rand, max sdk.Dec) sdk.Dec

RandomDecAmount generates a random decimal amount Note: The range of RandomDecAmount includes max, and is, in fact, biased to return max as well as 0.
