Struct CancelBroadcaster 

pub struct CancelBroadcaster { /* private fields */ }

Broadcasts cancel requests to multiple HTTP clients for redundancy.

This broadcaster fans out cancel requests to multiple pre-warmed HTTP clients in parallel, short-circuits when the first successful acknowledgement is received, and handles expected rejection patterns with appropriate log levels.

Implementations

impl CancelBroadcaster

pub fn new(config: CancelBroadcasterConfig) -> Result<Self>

Creates a new CancelBroadcaster with internal HTTP client pool.

Errors

Returns an error if any HTTP client fails to initialize.

pub async fn start(&self) -> Result<()>

Starts the broadcaster and health check loop.

Errors

Returns an error if the broadcaster is already running.

pub async fn stop(&self)

Stops the broadcaster and health check loop.

pub async fn broadcast_cancel( &self, instrument_id: InstrumentId, client_order_id: Option<ClientOrderId>, venue_order_id: Option<VenueOrderId>, ) -> Result<Option<OrderStatusReport>>

Broadcasts a single cancel request to all healthy clients in parallel.

Returns

• Ok(Some(report)) if successfully cancelled with a report.
• Ok(None) if the order was already cancelled (idempotent success).
• Err if all requests failed.

Errors

Returns an error if all cancel requests fail or no healthy clients are available.

pub async fn broadcast_batch_cancel( &self, instrument_id: InstrumentId, client_order_ids: Option<Vec<ClientOrderId>>, venue_order_ids: Option<Vec<VenueOrderId>>, ) -> Result<Vec<OrderStatusReport>>

Broadcasts a batch cancel request to all healthy clients in parallel.

Errors

Returns an error if all cancel requests fail or no healthy clients are available.

pub async fn broadcast_cancel_all( &self, instrument_id: InstrumentId, order_side: Option<OrderSide>, ) -> Result<Vec<OrderStatusReport>>

Broadcasts a cancel all request to all healthy clients in parallel.

Errors

Returns an error if all cancel requests fail or no healthy clients are available.

pub fn get_metrics(&self) -> BroadcasterMetrics

Gets broadcaster metrics.

pub async fn get_metrics_async(&self) -> BroadcasterMetrics

Gets broadcaster metrics (async version for use within async context).

pub fn get_client_stats(&self) -> Vec<ClientStats>

Gets per-client statistics.

pub async fn get_client_stats_async(&self) -> Vec<ClientStats>

Gets per-client statistics (async version for use within async context).

pub fn add_instrument(&self, instrument: InstrumentAny)

Adds an instrument to all HTTP clients in the pool for caching.

pub fn clone_for_async(&self) -> Self

Docstring for the class provided on the struct or enum.

const DOC: &'static CStr

Fully rendered class doc, including the text_signature if a constructor is defined.

type BaseType = PyAny

Base class

type ThreadChecker = SendablePyClass<CancelBroadcaster>

This handles following two situations:

type PyClassMutability = <<PyAny as PyClassBaseType>::PyClassMutability as PyClassMutability>::MutableChild

Immutable or mutable

type Dict = PyClassDummySlot

Specify this class has #[pyclass(dict)] or not.

type WeakRef = PyClassDummySlot

Specify this class has #[pyclass(weakref)] or not.

type BaseNativeType = PyAny

The closest native ancestor. This is PyAny by default, and when you declare #[pyclass(extends=PyDict)], it’s PyDict.
