README

meow

Golang implementation of the Meow hash, an extremely fast non-cryptographic hash.

go.dev Reference

Warning

The official implemention is in flux, therefore this one is too. The Travis CI build (config) tests against master branch of the reference implementation, therefore build status should be a good indicator of compatibility. This package is unlikely to be updated until the reference implementation stabilizes.

License

Zlib license following the official implemention.

Functions

func Checksum 

func Checksum(seed uint64, data []byte) [Size]byte

Checksum returns the Meow checksum of data.

Example 
package main

import (
	"fmt"

	"github.com/mmcloughlin/meow"
)

func main() {
	checksum := meow.Checksum(0, []byte("Hello, World!"))
	fmt.Printf("%x\n", checksum)
}

Output:

a8cfb4aad7eada8ef007aafe27135386

func Checksum32 

func Checksum32(seed uint64, data []byte) uint32

Checksum32 returns the 32-bit checksum of data.

func Checksum64 

func Checksum64(seed uint64, data []byte) uint64

Checksum64 returns the 64-bit checksum of data.

func New 

func New(seed uint64) hash.Hash

New returns a 128-bit Meow hash.

Example 
package main

import (
	"fmt"
	"io"

	"github.com/mmcloughlin/meow"
)

func main() {
	h := meow.New(0)
	io.WriteString(h, "Hello, ")
	io.WriteString(h, "World!")
	fmt.Printf("%x\n", h.Sum(nil))
}

Output:

a8cfb4aad7eada8ef007aafe27135386

func New32 

func New32(seed uint64) hash.Hash32

New32 returns the 32-bit version of Meow hash.
