xxHash64

Documentation

Overview

Package xxHash64 implements the very fast xxHash hashing algorithm (64 bits version). (https://github.com/Cyan4973/xxHash/)

Index

• func Checksum(input []byte, seed uint64) uint64
• func New(seed uint64) hash.Hash64

Examples

• Checksum
• New

Functions

func Checksum

func Checksum(input []byte, seed uint64) uint64

Checksum returns the 64bits Hash value.

Example

package main

import (
	"bytes"
	"fmt"
	"github.com/pierrec/xxHash/xxHash64"
)

func main() {
	buf := bytes.NewBufferString("this is a test")
	fmt.Printf("%x\n", xxHash64.Checksum(buf.Bytes(), 0xCAFE))
}

Output:

4228c3215949e862

func New

func New(seed uint64) hash.Hash64

New returns a new Hash64 instance.

Example

package main

import (
	"bytes"
	"fmt"
	"github.com/pierrec/xxHash/xxHash64"
)

func main() {
	buf := bytes.NewBufferString("this is a test")
	x := xxHash64.New(0xCAFE)
	x.Write(buf.Bytes())
	fmt.Printf("%x\n", x.Sum64())
}

Output:
