git submodule update --init
```

## Usage ##

Add this to your `Cargo.toml`:

```toml
[dependencies]
maxminddb = "0.13"
```

and this to your crate root:

extern crate maxminddb;
```

## API Documentation ##

The API docs are on [GitHub Pages](http://oschwald.github.io/maxminddb-rust/maxminddb/struct.Reader.html).

## Example ##

See [`examples/lookup.rs`](https://github.com/oschwald/maxminddb-rust/blob/master/examples/lookup.rs) for a basic example.

## Benchmarks ##

The projects include benchmarks using [Criterion.rs](https://github.com/bheisler/criterion.rs).

First you need to have a working copy of the GeoIP City database.
You can fetch it from [here](https://dev.maxmind.com/geoip/geoip2/geolite2/).

Place it in the root folder as `GeoIP2-City.mmdb`.

Once this is done, run

```
cargo bench
```

If [gnuplot](http://www.gnuplot.info/) is installed, Criterion.rs can generate
an HTML report displaying the results of the benchmark under
`target/criterion/report/index.html`.

Result of doing 100 random IP lookups:
