Types

type Source

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

Source is a random source using xorshift32 algorithm.

Marsaglia, George (July 2003). "Xorshift RNGs". Journal of Statistical Software. 8 (14).

Example

package main

import (
	"fmt"
	"math/rand"

	"github.com/shogo82148/randsrc/xorshift32"
)

func main() {
	src := xorshift32.New(1)
	r := rand.New(src)
	for i := 0; i < 10; i++ {
		fmt.Println(r.Int63())
	}
}

func New

func New(state uint32) *Source

New create a new source.

func (*Source) Int63

func (s *Source) Int63() int64

Int63 implements math/rand.Source.

func (*Source) Seed

func (s *Source) Seed(seed int64)

Seed implements math/rand.Source.

func (*Source) Uint32

func (s *Source) Uint32() uint32

Uint32 returns pseudo-random uint32 values in the range [0, 1<<32).

func (*Source) Uint64

func (s *Source) Uint64() uint64

Uint64 implements math/rand.Source64
