xxHash32

Documentation

Overview

Package xxHash32 implements the very fast xxHash hashing algorithm (32 bits version). (https://github.com/Cyan4973/xxHash/)

Index

• func Checksum(input []byte, seed uint32) uint32
• func New(seed uint32) hash.Hash32

Examples

• Checksum
• New

Functions

func Checksum

func Checksum(input []byte, seed uint32) uint32

Checksum returns the 32bits Hash value.

Example

package main

import (
	"bytes"
	"fmt"

	"blockwatch.cc/knoxdb/hash/xxHash32"
)

func main() {
	buf := bytes.NewBufferString("this is a test")
	fmt.Printf("%x\n", xxHash32.Checksum(buf.Bytes(), 0xCAFE))
}

Output:

bb4f02bc

func New

func New(seed uint32) hash.Hash32

New returns a new Hash32 instance.

Example

package main

import (
	"bytes"
	"fmt"

	"blockwatch.cc/knoxdb/hash/xxHash32"
)

func main() {
	buf := bytes.NewBufferString("this is a test")
	x := xxHash32.New(0xCAFE)
	x.Write(buf.Bytes())
	fmt.Printf("%x\n", x.Sum32())
}

Output:

bb4f02bc
