Functions ¶
func D ¶
D returns a random time.Duration between min and max: [min, max].
func Digits ¶
Digits returns a random string which contains only digits, and its length is `n`.
func Intn ¶
Intn returns an int number which is between 0 and max: [0, max).
Note that: 1. The `max` can only be greater than 0, or else it returns `max` directly; 2. The result is greater than or equal to 0, but less than `max`; 3. The result number is 32bit and less than math.MaxUint32.
func Letters ¶
Letters returns a random string which contains only letters, and its length is `n`.
func Meet ¶
Meet randomly calculate whether the given probability `num`/`total` is met.
func MeetProb ¶
MeetProb randomly calculate whether the given probability is met.
func N ¶
N returns a random int between min and max: [min, max]. The `min` and `max` also support negative numbers.
func Perm ¶
Perm returns, as a slice of n int numbers, a pseudo-random permutation of the integers [0,n). TODO performance improving for large slice producing.
func S ¶
S returns a random string which contains digits and letters, and its length is `n`. The optional parameter `symbols` specifies whether the result could contain symbols, which is false in default.
func Str ¶
Str randomly picks and returns `n` count of chars from given string `s`. It also supports unicode string like Chinese/Russian/Japanese, etc.
