# MurmurHash2 (64bit) implementation

[![Build Status](https://travis-ci.org/badboy/murmurhash64-rs.svg?branch=master)](https://travis-ci.org/badboy/murmurhash64-rs)

[![crates.io](http://meritbadge.herokuapp.com/murmurhash64)](https://crates.io/crates/murmurhash64)

Based on the implementation for Redis

([antirez/redis src/hyperloglog.c](https://github.com/antirez/redis/blob/93eed9ae0163e328c33b16ab9ea3c4fbe0f98674/src/hyperloglog.c#L390-L439))

More info and different implementations available at:

[Documentation](http://badboy.github.io/murmurhash64-rs/murmurhash64/)

## Build

```

cargo build --release

```

## Usage

```rust

use murmurhash64::murmur_hash64a;

fn main() {

    let key = "Pizza & Mandolino";

    let seed = 2915580697;

    let hash = murmur_hash64a(key.as_bytes(), seed);

}

```

As a `Hasher`

```rust

use std::collections::HashMap;

use murmurhash64::{MurmurHasher,RandomMurmurState};

use std::default::Default;

fn main() {

    let mut hashmap : HashMap<_, _, RandomMurmurState> = Default::default();

    hashmap.insert("abc", 123);

    hashmap.insert("def", 456);

    assert_eq!(Some(&123), hashmap.get("abc"));

    assert_eq!(Some(&456), hashmap.get("def"));

}

```
