Struct MarketSystem 

Source 
pub struct MarketSystem<H: MarketHook> { /* private fields */ }
Expand description

Market system (orchestrates market updates)

This system coordinates between service (pure logic), state (mutable data), and hooks (game-specific customization).

Implementations§

Source§

impl<H: MarketHook> MarketSystem<H>

Source

pub fn new(hook: H) -> Self

Create a new market system with hook

Source

pub async fn update_prices( &self, state: &mut MarketState, config: &MarketConfig, ) -> Vec<PriceChange>

Update all market prices

This performs a full market update:

  1. Calculate new prices from supply/demand
  2. Apply equilibrium drift
  3. Detect trends
  4. Call hooks
§Arguments
  • state - Mutable market state
  • config - Market configuration
§Returns

Vector of price changes that occurred

Source

pub async fn apply_event( &self, event: MarketEvent, state: &mut MarketState, config: &MarketConfig, )

Apply a market event

§Arguments
  • event - Market event to apply
  • state - Mutable market state
  • config - Market configuration
Source

pub fn get_items_by_trend( state: &MarketState, trend: MarketTrend, ) -> Vec<ItemId> ⓘ

Get items with specific trend

§Arguments
  • state - Market state
  • trend - Trend to filter by
§Returns

Vector of item IDs matching the trend

Source

pub fn set_demand_supply( state: &mut MarketState, item_id: &ItemId, demand: Option<f32>, supply: Option<f32>, )

Manually set demand/supply for an item

§Arguments
  • state - Mutable market state
  • item_id - Item to update
  • demand - New demand value (None = unchanged)
  • supply - New supply value (None = unchanged)
Source

pub fn get_market_summary(state: &MarketState) -> (f32, usize, usize)

Get market summary statistics

§Arguments
  • state - Market state
§Returns

Tuple of (average_price, total_items, volatile_items_count)
