## Usage

### Cargo

```toml

[dependencies]

geohash = "~0.1.1"
```

### Rust

extern crate geohash;

use geohash::{encode, decode}

fn main() {
    println!("encoding 37.8324, 112.5584: {}", encode(37.8324f32, 112.5584f32, 9u));
    let (lat, lon, _, _) = decode("ww8p1r4t8");
    println!("decoding ww8p1r4t8 to: {}, {}", lat, lon);
}
