Struct mango_v4::health::ScanningAccountRetriever
source · pub struct ScanningAccountRetriever<'a, 'info> { /* private fields */ }
Expand description
Takes a list of account infos containing
- an unknown number of Banks in any order, followed by
- the same number of oracles in the same order as the banks, followed by
- an unknown number of PerpMarket accounts
- the same number of oracles in the same order as the perp markets
- an unknown number of serum3 OpenOrders accounts
- an unknown number of openbook_v2 OpenOrders accounts
- an unknown number of fallback oracle accounts and retrieves accounts needed for the health computation by doing a linear scan for each request.
