## Development

You'll need to have [maturin](https://github.com/PyO3/maturin/) and [uv](https://github.com/astral-sh/uv) installed. Set up a local virtual environment in the `czv-python` folder by running:

```bash
uv venv
```

Make sure to activate the virtual environment (instructions should be provided in your terminal after running the previous command).

Once you've activated the virtual environment, install dependencies by running:

```bash
uv pip install -r requirements.txt
```

### Build package in local environment

```bash
maturin develop --uv --release
```

### Run tests

```bash
pytest
```
