        """Parse a list of candidate model `Generation` objects into a specific format.

        The return value is parsed from only the first `Generation` in the result, which
        is assumed to be the highest-likelihood `Generation`.

        Args:
            result: A list of `Generation` to be parsed.

                The `Generation` objects are assumed to be different candidate outputs
                for a single model input.
            partial: Whether to parse the output as a partial result.

                This is useful for parsers that can parse partial results.

        Returns:
            Structured output.
