pub fn encode(result: &AskResult) -> AskRowExpand description
Encode an AskResult as the single-row PG-wire result set.
Deterministic: re-running on byte-equal input is byte-equal output
(pinned by encode_is_deterministic_across_calls). Required by the
ASK determinism contract (#400) and by the cache-hit path (#403)
where the cached PG row must equal the freshly-encoded one.
