Functions

func Bytes

func Int

func Int() int

func Int63

func Int63() int64

func Seed

func Seed(seed int64)

func Str(length int) string

Types

type Rand

type Rand struct {
	sync.Mutex
	// contains filtered or unexported fields
}

Rand is a prng, that is seeded with OS randomness. The OS randomness is obtained from crypto/rand, however none of the provided methods are suitable for cryptographic usage. They all utilize math/rand's prng internally.

All of the methods here are suitable for concurrent use. This is achieved by using a mutex lock on all of the provided methods.

func NewRand

func NewRand() *Rand

func (*Rand) Bytes

func (r *Rand) Bytes(n int) []byte

Bytes returns n random bytes generated from the internal prng.

func (*Rand) Int

func (r *Rand) Int() int

func (*Rand) Int63

func (r *Rand) Int63() int64

func (*Rand) Seed

func (r *Rand) Seed(seed int64)

func (*Rand) Str

func (r *Rand) Str(length int) string

Str constructs a random alphanumeric string of given length.
