Functions ¶

func Int ¶

func Int() (int, error)

Int returns a non-negative uniform random value as int.

func IntN ¶

func IntN(max int) (int, error)

IntN returns a uniform random value in [0, max). It panics if max <= 0.

func MustNumeric ¶

func MustNumeric(num int) int

MustNumeric returns a cryptographically secure random number in the range of [0, num).

func MustString ¶

func MustString(l int, allowedRunes []rune) string

MustString returns a cryptographically secure random string sequence using the defined runes.

Panics on error.

func RuneSequence ¶

func RuneSequence(l int, allowedRunes []rune) ([]rune, error)

RuneSequence returns a cryptographically secure random sequence using the defined allowed runes.

func Uint32 ¶

func Uint32() (uint32, error)

Uint32 returns a uniform random value as uint32.

func Uint32N ¶

func Uint32N(max uint32) (uint32, error)

Uint32N returns a uniform random value in [0, max). It panics if max <= 0.

func Uint64 ¶

func Uint64() (uint64, error)

Uint64 returns a uniform random value as uint64.

func Uint64N ¶

func Uint64N(max uint64) (uint64, error)

Uint64N returns a uniform random value in [0, max). It panics if max <= 0.
