Struct MarketLoad 

pub struct MarketLoad { /* private fields */ }

Loads and screens one market at each update, for a router.

Make a new load at each update, with the mints just read. Fetch what missing names, insert each account that the fetch gives, and call missing again. When it is empty, call finish. missing names each account once. Insert nothing for an account that the router cannot fetch: a direction that reads it does not route.

Declare LoadedMarket::declare for the next update. A router that serves only declared accounts then loads one more link of a chain of reads at each update.

Implementations

impl MarketLoad

pub fn new(args: MarketLoadArgs) -> Self

pub fn missing(&mut self) -> Result<Vec<Address>, HookError>

The accounts to fetch next: what MintInfo::missing names for each mint, and what the screens lack. It leaves out each account that it named before. Empty when the load can learn nothing more.

Errors

The error of MintInfo::missing.

pub fn insert(&mut self, address: Address, account: Option<FetchedAccount>)

Records what a fetch of address gave: None for no account. A mint whose MintInfo::missing names it also holds it.

pub fn finish(self) -> LoadedMarket
