Fields

configuration: MarketConfiguration

borrow_asset_deposited_active: BorrowAssetAmount

Total amount of borrow asset earning interest in the market.

borrow_asset_deposited_incoming: Vec<IncomingDeposit>

Upcoming snapshot indices with amounts of borrow asset that will be activated.

borrow_asset_withdrawal_in_flight: BorrowAssetAmount

borrow_asset_borrowed_in_flight: BorrowAssetAmount

Sending borrow asset out, because if somebody sends the contract borrow asset, it’s ok for the contract to attempt to fulfill withdrawal request, even if the market thinks it doesn’t have enough to fulfill.

borrow_asset_borrowed: BorrowAssetAmount

Amount of borrow asset that has been withdrawn (is in use by) by borrowers.

borrow_asset_deposited_active - borrow_asset_borrowed - borrow_asset_borrowed_in_flight >= 0 should always be true.

collateral_asset_deposited: CollateralAssetAmount

Market-wide collateral asset deposit tracking.

current_time_chunk: TimeChunk

current_yield_distribution: BorrowAssetAmount

finalized_snapshots: ChunkedAppendOnlyList<Snapshot, 32>

withdrawal_queue: WithdrawalQueue

static_yield: LookupMap<AccountId, Accumulator<BorrowAsset>>
