This library is a fully featured `\Generator` based Collection implementation. The goal is to provide a memory efficient fast collection implementation that makes it possible to use familiar collection methods to work with infinite or very large streams.

Our tests were largely copied from [`tightenco/collect`](https://packagist.org/packages/tightenco/collect) with many modifications added to support the deferred processing you get with `Generators`.

For basic usage, see [the `AllMethods.php` example](examples/AllMethods.php)
