pub fn parse_outcome_instruments(
meta: &OutcomeMeta,
) -> Result<Vec<HyperliquidInstrumentDef>, String>Expand description
Parse outcome instrument definitions from Hyperliquid outcomeMeta response.
Each OutcomeMarket yields two definitions, one per side (0 and 1),
modeled as binary outcome side tokens. The Nautilus internal symbol uses
the form {outcome_index}-{YES|NO}-OUTCOME (symmetric with -PERP /
-SPOT), and the wire raw_symbol uses the spot-coin form
(#<encoding>) which is what l2Book, trades, and bbo subscriptions
accept.
Expiry is read from the market’s own description when it carries
class:priceBinary; for outcomes that point at a parent question (other
or index:N), the expiry is inherited from that question’s description.
side_name is taken from the venue’s sideSpecs entry when present,
otherwise it falls back to the canonical HIP-4 labels ("Yes" / "No").
