| |
| ## How to contribute |
| |
| - Fix a bug or implement a new thing |
| - Include tests for your new feature, preferably a QuickCheck test |
| - Make a Pull Request |
| |
| For new features, please first consider filing a PR to [rust-lang/rust](https://github.com/rust-lang/rust), |
| adding your new feature to the `Iterator` trait of the standard library, if you believe it is reasonable. |
| If it isn't accepted there, proposing it for inclusion in ``itertools`` is a good idea. |
| The reason for doing is this is so that we avoid future breakage as with ``.flatten()``. |
| However, if your feature involves heap allocation, such as storing elements in a ``Vec<T>``, |
| then it can't be accepted into ``libcore``, and you should propose it for ``itertools`` directly instead. |
