    This evaluator computes a normalized Damerau-Levenshtein distance between two JSON strings
    after parsing them and converting them to a canonical format (i.e., whitespace and key order are normalized).
    It can be customized with alternative distance and canonicalization functions.

    Attributes:
        _string_distance (Callable[[str, str], float]): The internal distance computation function.
        _canonicalize (Callable[[Any], Any]): The internal canonicalization function.

    Examples:
        >>> evaluator = JsonEditDistanceEvaluator()
        >>> result = evaluator.evaluate_strings(
        ...     prediction='{"a": 1, "b": 2}', reference='{"a": 1, "b": 3}'
        ... )
        >>> assert result["score"] is not None

    Raises:
        ImportError: If `rapidfuzz` is not installed and no alternative `string_distance` function is provided.

        Args:
            string_distance: A callable that computes the distance between two strings.
                If not provided, a Damerau-Levenshtein distance from the `rapidfuzz`
                package will be used.
            canonicalize: A callable that converts a parsed JSON object into its
                canonical string form.
                If not provided, the default behavior is to serialize the JSON with
                sorted keys and no extra whitespace.

        Raises:
            ImportError: If the `rapidfuzz` package is not installed and no
                `string_distance` function is provided.
