Types

type Source

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

Source is a random source using xorshift64+ algorithm.

Example

package main

import (
	"fmt"
	"math/rand"

	"github.com/shogo82148/randsrc/xorshift64p"
)

func main() {
	src := xorshift64p.New(1, 2)
	r := rand.New(src)
	for i := 0; i < 10; i++ {
		fmt.Println(r.Int63())
	}
}
