Struct WsDispatchState

Source

pub struct WsDispatchState {
    pub order_identities: DashMap<ClientOrderId, OrderIdentity>,
    pub emitted_accepted: DashSet<ClientOrderId>,

Expand description

Shared state for cross-stream event deduplication between the private and business WebSocket dispatch loops.

Uses DashMap/DashSet for concurrent access from both stream tasks and the main thread without mutex contention.

Fields§

§order_identities: DashMap<ClientOrderId, OrderIdentity>§emitted_accepted: DashSet<ClientOrderId>§triggered_orders: DashSet<ClientOrderId>§filled_orders: DashSet<ClientOrderId>§emitted_trades: DashSet<TradeId>

Implementations§

Source §

impl WsDispatchState

Source

pub fn check_and_insert_trade(&self, trade_id: TradeId) -> bool

Returns true if this trade was already emitted (duplicate). Uses atomic insert to avoid TOCTOU races between concurrent streams.
