    Parameters
    ----------

    url : str
        GCS URL to download. This should begin with 'gs://'.

    altexts : None or list of str
        If not None, this is a list of alternate extensions to try for the file
        other than the one provided in `filename`. For example, to get anything
        that's an .sqlite where .sqlite.gz is expected, use altexts=[''] to
        strip the .gz.

    client : google.cloud.storage.Client instance
        The instance of the Client to use to perform the download operation. If
        this is None, a new Client will be used. If this is None and
        `service_account_json` points to a downloaded JSON file with GCS
        credentials, a new Client with the provided credentials will be used. If
        this is not None, the existing Client instance will be used.

    service_account_json : str
        Path to a downloaded GCS credentials JSON file.

    raiseonfail : bool
        If True, will re-raise whatever Exception caused the operation to fail
        and break out immediately.

    Returns
    -------

    str
        Path to the downloaded filename or None if the download was
        unsuccessful.
