We represent an IntegerArray with 2 numpy arrays: - data: contains a numpy integer array of the appropriate dtype - mask: a boolean array holding a mask on the data, True is missing To construct an IntegerArray from generic array-like input, use :func:`pandas.array` with one of the integer dtypes (see examples). See :ref:`integer_na` for more. Parameters ---------- values : numpy.ndarray A 1-d integer-dtype array. mask : numpy.ndarray A 1-d boolean-dtype array indicating missing values. copy : bool, default False Whether to copy the `values` and `mask`.
