Implementations

impl Marketplace

pub fn new(fee_bps: u64, protocol_fee_address: String) -> Marketplace

pub fn place_order( &mut self, maker: &str, side: OrderSide, sell_asset: MarketAsset, buy_asset: MarketAsset, amount: u64, price: u64, ) -> String

Place a limit order. Returns the order ID.

pub fn cancel_order(&mut self, order_id: &str) -> bool

Cancel an open order. Returns true if found and cancelled.

pub fn get_order(&self, order_id: &str) -> Option<&Order>

Get a single order.

pub fn order_book( &self, sell_asset: &MarketAsset, buy_asset: &MarketAsset, ) -> OrderBook

Get the order book for a given asset pair.

pub fn orders_for_maker(&self, maker: &str) -> Vec<&Order>

Get all orders for a maker.

pub fn try_match( &mut self, maker: &str, side: OrderSide, sell_asset: &MarketAsset, buy_asset: &MarketAsset, amount: u64, price: u64, ) -> Vec<Trade>

Try to match a new sell order against existing buy orders (and vice versa). Returns the trades that were executed. This is a simple price-time priority matching engine.

pub fn place_and_match( &mut self, maker: &str, side: OrderSide, sell_asset: MarketAsset, buy_asset: MarketAsset, amount: u64, price: u64, ) -> (String, Vec<Trade>)

Place an order and immediately attempt to match it. Returns the order ID and any trades that were executed.

pub fn trades(&self) -> &[Trade]
