D returns a random time.Duration between min and max: [min, max].

func (*Rand) GetDigits 

func (my *Rand) GetDigits(n int) string

GetDigits returns a random str which contains only digits, and its length is `n`.

func (*Rand) GetLetters 

func (my *Rand) GetLetters(n int) string

GetLetters returns a random str which contains only letters, and its length is `n`.

func (*Rand) GetString 

func (my *Rand) GetString(s string, n int) string

GetString randomly picks and returns `n` count of chars from given str `s`. It also supports unicode str like Chinese/Russian/Japanese, etc.

func (*Rand) GetSymbols 

func (my *Rand) GetSymbols(n int) string

GetSymbols returns a random str which contains only symbols, and its length is `n`.

func (*Rand) Intn 

func (my *Rand) Intn(max int) int

func (*Rand) Meet 

func (my *Rand) Meet(num, total int) bool

Meet randomly calculate whether the given probability `num`/`total` is met.

func (*Rand) MeetProb 

func (my *Rand) MeetProb(prob float32) bool

MeetProb randomly calculate whether the given probability is met.

func (*Rand) N 

func (my *Rand) N(min, max int) int
