[![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))

## 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"));
}
```
