}Expand description
Shared, immutable (from the manager’s perspective) dependencies.
The engine owns these fields and lends &EngineDeps to sub-managers
so they can read caches, services, and configuration without owning clones.
Fields§
§mmp_cache: Option<Arc<MmpCache>>MMP (Market Maker Protection) cache.
tier_cache: Option<Arc<TierCache>>Tier cache for position-limit and margin-mode lookups.
portfolio_service: Option<Arc<dyn PortfolioService + Send + Sync>>Canonical source of truth for executed positions and cash.
portfolio_cache: Option<Arc<PortfolioCache>>Portfolio cache for synchronous fill application in the engine hot path.
risk_account_builder: Option<Arc<RiskAccountBuilder>>Single source of truth for building a risk-ready Account for PM.
standard_account_builder: Option<Arc<StandardAccountBuilder>>Builder for Standard margin mode accounts.
greeks_cache: Option<Arc<GreeksCache>>Spot price provider for margin calculations (legacy / test fallback).
mark_price_oracles: HashMap<String, Arc<HyperliquidMarkPriceOracle>>Mark price oracles keyed by underlying (e.g. “BTC”, “ETH”).
reference_prices: HashMap<String, f64>Legacy reference prices for test / expiry settlement fallback.
liquidation_cache: Option<Arc<LiquidationCache>>Pre-liquidation order blocking cache.
config: ConfigEngine configuration (scenarios, fee config, tolerances, etc.).
portfolio_margin_pool_enabled: boolGlobal PM settlement-pool expiry classification gate.
portfolio_margin_settlement_allowlist: BTreeSet<WalletAddress>Wallets allowed to use PM settlement-pool expiry classification.
event_sender: UnboundedSender<EngineMessage>Broadcast channel for engine events (order updates, L2, trades, …). Goes to EventBus for persistence and cross-service sync.
ws_event_sender: Option<UnboundedSender<EngineMessage>>Direct channel for WebSocket event forwarding.
When set, events are sent here in addition to event_sender so that the
WsEventForwarder receives them with minimal latency.
margin_timestamp_s: i64Current command timestamp in seconds. Set from CommandEnvelope.received_ts_ms at the top of apply(). Used by SPAN instead of wall clock for deterministic time-to-expiry calculations.
liquidation_states: HashMap<WalletAddress, LiquidationStateType>Internal liquidation state per wallet, updated by LiquidationState commands.
wallet_margin_modes: HashMap<WalletAddress, MarginMode>Internal margin mode per wallet, updated by TierUpdate commands.
mmp_enabled: HashMap<(WalletAddress, String), bool>Internal MMP enabled state per (wallet, currency), updated by MmpConfigUpdate commands.
wallet_trading_limits: HashMap<WalletAddress, TradingLimits>Internal trading limits per wallet, seeded from tier_cache at startup. Updated by TierUpdate commands.
default_trading_limits: TradingLimitsConfigured fallback trading limits for wallets without explicit tier rows.
wallet_tiers: HashMap<WalletAddress, String>Internal tier string per wallet (e.g. “tier1”, “tier2”, “market_maker”). Seeded from tier_cache at startup, updated by TierUpdate commands.
perp_positions: HashMap<(String, String), PerpPosition>Internal perp positions per (account, coin), updated by HypercorePositionUpdate commands. Keyed by (lowercase account string, coin string).
hypercore_account_equity: HashMap<WalletAddress, Decimal>HyperCore account equity per wallet (manager address), updated by
HypercoreEquityUpdate commands from the Hydromancer feed. For PM users,
this replaces the balance_ledger as the cash base for margin calculations.
The value is the HyperCore accountValue which includes perp UPNL.
hypercore_equity_timestamps: HashMap<WalletAddress, u64>Last applied HyperCore equity update timestamp per wallet, in milliseconds. Written by the Hydromancer HyperCore sync path and restored from snapshots so runtime apply and replay reject stale accountValue updates.
Implementations§
Source§impl EngineDeps
impl EngineDeps
Sourcepub fn emit_event(&self, event: &EngineMessage)
pub fn emit_event(&self, event: &EngineMessage)
Emit an engine event to both the event bus (persistence) and the direct WS channel.
Both paths are best-effort (errors silently dropped). A dropped WS receiver just means no WS clients.
