    Most methods are implemented using `pyarrow compute functions. <https://arrow.apache.org/docs/python/api/compute.html>`__
    Some methods may either raise an exception or raise a ``PerformanceWarning`` if an

        skipna : bool, default True
            Exclude NA values. If the entire array is NA and `skipna` is
            True, then the result will be True, as for an empty array.
            If `skipna` is False, the result will still be False if there is
            at least one element that is falsey, otherwise NA will be returned
            if there are NA's present.

        Returns
        -------
        bool or :attr:`pandas.NA`

        Examples
        --------
        The result indicates whether all elements are truthy (and by default
        skips NAs):

        >>> pd.array([True, True, pd.NA], dtype="boolean[pyarrow]").all()
        True
        >>> pd.array([1, 1, pd.NA], dtype="boolean[pyarrow]").all()
        True
        >>> pd.array([True, False, pd.NA], dtype="boolean[pyarrow]").all()
        False
        >>> pd.array([], dtype="boolean[pyarrow]").all()
        True
        >>> pd.array([pd.NA], dtype="boolean[pyarrow]").all()
        True
        >>> pd.array([pd.NA], dtype="float64[pyarrow]").all()
        True

        With ``skipna=False``, the result can be NA if this is logically
        required (whether ``pd.NA`` is True or False influences the result):

        >>> pd.array([True, True, pd.NA], dtype="boolean[pyarrow]").all(skipna=False)
        <NA>
        >>> pd.array([1, 1, pd.NA], dtype="boolean[pyarrow]").all(skipna=False)
        <NA>
        >>> pd.array([True, False, pd.NA], dtype="boolean[pyarrow]").all(skipna=False)
        False

        allow_fill : bool, default False
            How to handle negative values in `indices`.

            * False: negative values in `indices` indicate positional indices
              from the right (the default). This is similar to

            * True: negative values in `indices` indicate

              other negative values raise a ``ValueError``.

        fill_value : any, optional
            Fill value to use for NA-indices when `allow_fill` is True.
            This may be ``None``, in which case the default NA value for
            the type, ``self.dtype.na_value``, is used.

            For many ExtensionArrays, there will be two representations of
            `fill_value`: a user-facing "boxed" scalar, and a low-level
            physical NA value. `fill_value` should be the user-facing version,
            and the implementation should handle translating that to the
            physical version for processing the take if necessary.
