Struct ExchangeClient 

pub struct ExchangeClient { /* private fields */ }

Unified exchange client that wraps per-capability trait objects.

Created by super::VenueRegistry::create_exchange_client. Provides capability discovery and a convenience fetch_market_snapshot that fetches all available data in parallel.

Implementations

impl ExchangeClient

pub fn from_descriptor(desc: &VenueDescriptor) -> Self

👎Deprecated since 0.8.0:

pass the transport: use ExchangeClient::from_descriptor_with_http

Build an ExchangeClient from a VenueDescriptor.

Each capability that exists in the descriptor gets a ConfigurableExchangeClient implementation wired in.

pub fn from_descriptor_with_http( desc: &VenueDescriptor, http: Arc<dyn HttpClient>, ) -> Self

Build an ExchangeClient from a VenueDescriptor whose requests go through http.

pub fn venue_id(&self) -> &str

Venue ID (e.g., “binance”).

pub fn venue_name(&self) -> &str

Venue display name (e.g., “Binance Spot”).

pub fn venue_symbol(&self, pair: &Pair) -> String

The venue’s symbol for a pair; a pair with no quote uses the venue’s default quote.

pub fn has_order_book(&self) -> bool

Whether this client supports order book fetching.

pub fn has_ticker(&self) -> bool

Whether this client supports ticker fetching.

pub fn has_trade_history(&self) -> bool

Whether this client supports trade history fetching.

pub fn has_ohlc(&self) -> bool

Whether this client supports OHLC / kline data.

pub async fn fetch_order_book(&self, pair: &str) -> Result<OrderBook>

Fetch order book (if supported).

pub async fn fetch_ticker(&self, pair: &str) -> Result<Ticker>

Fetch ticker (if supported).

pub async fn fetch_recent_trades( &self, pair: &str, limit: u32, ) -> Result<Vec<Trade>>

Fetch recent trades (if supported).

pub fn lists_assets(&self) -> bool

Whether the venue lists its coins’ contracts (assets).

pub async fn fetch_assets(&self) -> Option<Result<Vec<AssetInfo>>>

The venue’s coin list, or None when the venue has no assets capability.

pub async fn fetch_token_addresses( &self, pair: &Pair, ) -> Option<Result<Vec<TokenAddress>>>

The token lines for pair from the venue’s coin list, or None when the venue has no assets capability.

pub async fn fetch_ohlc( &self, pair: &str, interval: &str, limit: u32, ) -> Result<Vec<Candle>>

Fetch OHLC candlesticks (if supported).

pub async fn fetch_market_snapshot( &self, pair: &str, trades_limit: u32, ) -> MarketSnapshot

Fetch all available market data for a pair in one call, with up to trades_limit recent trades.

Each capability is fetched independently; failures in one capability do not prevent others from succeeding (they just produce None).
