pub fn parse_metadata(
ctx: &mut SpendContext,
launcher_solution: &Program,
) -> Result<OptionMetadata>Expand description
Recover an option’s OptionMetadata (expiry seconds + strike type) from the launcher coin’s
solution, which the caller fetched from a node/indexer.
The launcher solution carries the option’s key-value metadata; this decodes it into the
caller-owned SpendContext. Network-free: the caller supplies the serialized solution.
