Struct WsDispatchState 

pub struct WsDispatchState { /* private fields */ }

Shared dispatch state for the Derive WS execution loop.

order_identities populates on successful submit_order and is consulted by both the .orders and .trades dispatch paths to decide whether a frame belongs to a tracked or external order. pending_modifies and bound_venue_order_ids track the in-flight and current venue order id of a private/replace so the dispatch suppresses events for the superseded leg.

Implementations

impl WsDispatchState

pub fn new() -> Self

pub fn register_identity( &self, client_order_id: ClientOrderId, identity: OrderIdentity, )

Registers an order identity captured at submission so subsequent WS frames for the same client_order_id resolve to the tracked path.

pub fn identity(&self, client_order_id: &ClientOrderId) -> Option<OrderIdentity>

Returns the registered identity for a client order, when one was captured at submission time.

pub fn forget(&self, client_order_id: &ClientOrderId)

Drops identity and the accepted marker for a terminal order so future stale frames (post-cancel cleanup, history backfill) take the untracked report path.

pub fn record_venue_order_id( &self, client_order_id: ClientOrderId, venue_order_id: VenueOrderId, )

Records the venue order id currently bound to a tracked client order.

pub fn bound_venue_order_id( &self, client_order_id: &ClientOrderId, ) -> Option<VenueOrderId>

Returns the venue order id currently bound to a tracked client order.

pub fn mark_pending_modify( &self, client_order_id: ClientOrderId, old_venue_order_id: VenueOrderId, )

Records the old venue order id of an in-flight private/replace, set before the request so the cancel leg is suppressed.

pub fn clear_pending_modify(&self, client_order_id: &ClientOrderId)

Clears the in-flight modify marker once the replace resolves.

pub fn pending_modify( &self, client_order_id: &ClientOrderId, ) -> Option<VenueOrderId>

Returns the old venue order id of an in-flight modify, when one is set.

pub fn contains_accepted(&self, client_order_id: &ClientOrderId) -> bool

Returns true when an OrderAccepted has already been emitted for this client order in the current process lifetime.

pub fn mark_accepted(&self, client_order_id: ClientOrderId) -> bool

Records that OrderAccepted has been emitted for this client order. Returns true when the marker was already present (duplicate).

pub fn contains_filled(&self, client_order_id: &ClientOrderId) -> bool

Returns true when this client order has reached a terminal filled state, used to suppress stale Accepted frames replayed on reconnect.

pub fn mark_filled(&self, client_order_id: ClientOrderId)

Marks the client order as terminally filled. Idempotent.

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

Inserts the trade id atomically. Returns true when the id was already present (i.e., this fill should be skipped as a duplicate).

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

Returns true when this trade id has already been seen, without mutating state.
