Types

type Rand

type Rand struct {
	tmsync.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) Bool

    func (r *Rand) Bool() bool

      Bool returns a uniformly random boolean

      func (*Rand) Bytes

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

        Bytes returns n random bytes generated from the internal prng.

        func (*Rand) Float32

        func (r *Rand) Float32() float32

        func (*Rand) Float64

        func (r *Rand) Float64() float64

        func (*Rand) Int

        func (r *Rand) Int() int

        func (*Rand) Int16

        func (r *Rand) Int16() int16

        func (*Rand) Int31

        func (r *Rand) Int31() int32

        func (*Rand) Int31n

        func (r *Rand) Int31n(n int32) int32

        func (*Rand) Int32

        func (r *Rand) Int32() int32

        func (*Rand) Int63

        func (r *Rand) Int63() int64

        func (*Rand) Int63n

        func (r *Rand) Int63n(n int64) int64

        func (*Rand) Int64

        func (r *Rand) Int64() int64

        func (*Rand) Intn

        func (r *Rand) Intn(n int) int

          Intn returns, as an int, a uniform pseudo-random number in the range [0, n). It panics if n <= 0.

          func (*Rand) Perm

          func (r *Rand) Perm(n int) []int

            Perm returns a pseudo-random permutation of n integers in [0, n).

            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.

              func (*Rand) Time

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

              func (*Rand) Uint

              func (r *Rand) Uint() uint

              func (*Rand) Uint16

              func (r *Rand) Uint16() uint16

              func (*Rand) Uint32

              func (r *Rand) Uint32() uint32

              func (*Rand) Uint64

              func (r *Rand) Uint64() uint64
