Expand description

Commands sent from the outer client to the inner message handler.

Variants§

§

SetClient(WebSocketClient)

Set the WebSocket client for this handler.

§

Disconnect

Disconnect the WebSocket connection.

§

ReplaySubscriptions

Replay all subscriptions after a reconnection.

§

Subscribe

Subscribe to market data for a symbol.

Fields

§request_id: i64

Request ID for correlation.

§symbol: Ustr

Instrument symbol.

§spec: AxMdSubscriptionSpec

Market data subscription options.

§

WriteBook

Writes a book subscription on the current connection, opening gate once written.

With an unsubscribe request ID, first unsubscribes the symbol so the venue restarts its stream with a snapshot. That acknowledgement stays untracked, keeping the topic desired for reconnect replay. The write always runs, since the subscription state already counts it; cancel only keeps the gate closed.

Fields

§request_id: i64

Request ID for correlation.

§unsubscribe_request_id: Option<i64>

Request ID of the unsubscribe that replaces an open stream.

§symbol: Ustr

Instrument symbol.

§spec: AxMdSubscriptionSpec

Market data subscription options.

§cancel: CancellationToken

Keeps the gate closed once cancelled.

§gate: SnapshotGate

Snapshot gate opened once the write completes.

§completion: Sender<Result<(), AxWsClientError>>

Receives the write result.

§

Unsubscribe

Unsubscribe from market data for a symbol.

Fields

§request_id: i64

Request ID for correlation.

§symbol: Ustr

Instrument symbol.

§topic: String

Subscription topic for state tracking.

§

SubscribeCandles

Subscribe to candle data for a symbol.

Fields

§request_id: i64

Request ID for correlation.

§symbol: Ustr

Instrument symbol.

§width: AxCandleWidth

Candle width/interval.

§

UnsubscribeCandles

Unsubscribe from candle data for a symbol.

Fields

§request_id: i64

Request ID for correlation.

§symbol: Ustr

Instrument symbol.

§width: AxCandleWidth

Candle width/interval.

§topic: String

Subscription topic for state tracking.
