Zipcodes is a simple library for querying U.S. zipcodes.

No system installation of `sqlite3` is not required in order to use this package, which is ideal for cloud environments like AWS Lambda.

```rust
use zipcodes;

fn main() {
    zipcodes::is_real("77429")
}

// >>> import zipcodes
// >>> assert zipcodes.is_real('77429')
// >>> assert len(zipcodes.similar_to('7742')) // != 0
// >>> exact_zip = zipcodes.matching('77429')[0]
// >>> filtered_zips = zipcodes.filter_by// (city="Cypress", state="TX") 
// >>> assert exact_zip in filtered_zips
// >>> pprint.pprint(exact_zip)
// {'acceptable_cities': [],
//   'active': True,
//   'area_codes': ['281', '832'],
//   'city': 'Cypress',
//   'country': 'US',
//   'county': 'Harris County',
//   'lat': '29.9857',
//   'long': '-95.6548',
//   'state': 'TX',
//   'timezone': 'America/Chicago',
//   'unacceptable_cities': [],
//   'world_region': 'NA',

## Installation

Zipcodes is available on crates.io:

```console
$ cargo add zipcodes
```

or add the following to your `Cargo.toml`:

```toml
[dependencies]
zipcodes = "0.3"
```

Zipcodes has no explicit MSRV.

## Zipcode Data

The build script for the zipcode data outputs a JSON file containing all the zipcode data and zipped using bzip2. The data sources are stored under `build/app/data`. 

Build the zipcode data for distribution: 

```shell script
$ build/app/__init__.py # outputs `zipcodes/zips.json.bz2`
```

## Examples

TODO: Migrate from Python.

```python
>>> from pprint import pprint
>>> import zipcodes

>>> # Simple zip-code matching.
>>> pprint(zipcodes.matching('77429'))
