impl ManageOrder for HyperliquidClient

async fn place_order( &self, symbol: String, price: Decimal, volume: Decimal, ) -> Result<i64, String>

place order, return cloid

async fn change_order_by_cloid( &self, cloid: i64, price: Decimal, volume: Decimal, ) -> Result<i64, String>

change order

async fn cancel_order(&self, cloid: i64) -> Result<i64, String>

cancel order by cloid

async fn cancel_all_order(&self) -> Result<bool, String>

cancel all order regardless of cloid/symbol

impl SubscribeMarketData for HyperliquidClient

fn subscribe_l2_update(&self, symbol: String) -> BoxStream<L2Update>

Streams L2 orderbook updates for symbol. Each message from Hyperliquid is a full-depth snapshot; every level is emitted as an individual L2Update event. All levels in the same snapshot share the same sequence value.

fn subscribe_asset_context(&self, symbol: String) -> BoxStream<AssetContext>

Streams asset context updates for symbol via Hyperliquid’s activeAssetCtx subscription. Each message carries OI, funding rate, mark price, and 24h notional volume.

fn subscribe_liquidation(&self, user: String) -> BoxStream<Liquidation>

Streams liquidation events for a user address via Hyperliquid’s userEvents subscription. Note: Hyperliquid’s liquidation event is account-level; symbol is set to empty string and side defaults to OrderSide::Sell as the data source does not provide per-position detail.

fn subscribe_fill(&self, symbol: String) -> BoxStream<Fill>

Streams public trade fills for symbol. Maps to Hyperliquid’s trades subscription. side reflects the aggressor: “B” (buyer) → OrderSide::Buy, otherwise → OrderSide::Sell.

impl TestServer for HyperliquidClient

async fn ping(&self) -> Result<bool, String>

Sends a lightweight allMids request; returns true if the server responds 200 OK.

async fn get_server_time(&self) -> Result<i64, String>
