var RandProvider = NewPseudoRandom()

RandProvider is the default random number generator the api will use.

Types

type PseudoRandom

type PseudoRandom struct {
	// contains filtered or unexported fields
}

PseudoRandom implements the Random interface using the built-in rand package.

func (*PseudoRandom) Intn

func (p *PseudoRandom) Intn(lower, upper int) int

Intn generates a random integer in the [lower, upper) half-open interval. If upper < lower it panics.

type Random

type Random interface {
	// Intn generates a random integer in the [lower, upper)
	// half-open interval.
	Intn(lower, upper int) int
}

Random provides functions to generate random numbers

func NewPseudoRandom

func NewPseudoRandom() Random

NewPseudoRandom returns a new Random backed by the PseudoRandom implementation.
