Struct NoOpExchange 

pub struct NoOpExchange { /* private fields */ }

Minimal exchange that does nothing - used internally by PaperExchange::new_standalone() All quotes come from queue_quotes/inject_quote, not from this exchange.

Implementations

impl NoOpExchange

pub fn new() -> Self

Create a no-op testnet paper exchange identity.

pub fn with_exchange_id(id: &str) -> Self

Create with a custom exchange ID (for backtest mode matching production exchange)

pub fn with_config(id: &str, environment: Environment) -> Self

Create with custom exchange ID and environment (for full compatibility)

Trait Implementations

impl Default for NoOpExchange

fn default() -> Self

Returns the “default value” for a type.

impl Exchange for NoOpExchange

fn exchange_id(&self) -> &ExchangeId

Get the exchange ID

fn environment(&self) -> Environment

Get the environment (mainnet/testnet)

fn place_orders<'life0, 'life1, 'async_trait>( &'life0 self, _orders: &'life1 [OrderInput], ) -> Pin<Box<dyn Future<Output = Result<Vec<PlaceOrderResult>, ExchangeError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Place multiple limit orders in a single batch API call. Returns a Vec of results, one for each order in the same order as the input.

fn cancel_order<'life0, 'life1, 'life2, 'life3, 'life4, 'async_trait>( &'life0 self, _instrument: &'life1 InstrumentId, _market_index: &'life2 MarketIndex, _client_id: &'life3 ClientOrderId, _exchange_order_id: Option<&'life4 ExchangeOrderId>, ) -> Pin<Box<dyn Future<Output = Result<(), ExchangeError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, 'life3: 'async_trait, 'life4: 'async_trait,

Cancel an order by client_id or exchange_order_id.

fn cancel_all_orders<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _instrument: &'life1 InstrumentId, _market_index: &'life2 MarketIndex, ) -> Pin<Box<dyn Future<Output = Result<u32, ExchangeError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Cancel all orders for an instrument. Returns number of orders canceled.

fn poll_user_fills<'life0, 'life1, 'async_trait>( &'life0 self, _cursor: Option<&'life1 str>, ) -> Pin<Box<dyn Future<Output = Result<Vec<Fill>, ExchangeError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Poll user fills since cursor. This is the primary execution event source. cursor is opaque string (implementation-specific).

fn poll_quotes<'life0, 'life1, 'async_trait>( &'life0 self, _instruments: &'life1 [InstrumentId], ) -> Pin<Box<dyn Future<Output = Result<Vec<Quote>, ExchangeError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

Poll current quotes/prices.

fn poll_account_state<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<AccountState, ExchangeError>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Poll account state (absolute). Used for snapshot-based synchronization.

fn instance(&self) -> ExchangeInstance

Get the exchange instance key

fn init<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<(), ExchangeError>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Initialize the exchange connection and perform startup validations. Called by the runner before entering the main loop. Implementations can validate: connectivity, vault ownership, account balance, etc.
