Asset manager

Implementations

impl AssetManager

pub fn new() -> Self

pub fn initialize(&mut self) -> Result<(), FinancialError>

pub fn register_price_feed(&mut self, feed: PriceFeed)

Register a price feed. The feed is keyed by its asset_id so that ingest_from_feed(asset_id) can locate it. Re-registering a feed for the same asset replaces the prior one.

pub fn update_price_history(&mut self, asset_id: &str, prices: Vec<f64>)

Directly set the cached price history (oldest first) for asset_id. This is the manual entry point; ingest_from_feed is the feed-driven one. The history is held in the manager’s cache until apply_to_asset copies it onto an Asset.

pub fn get_price_history(&self, asset_id: &str) -> Option<&Vec<f64>>

Look up the cached price history for asset_id, if any.

pub fn ingest_from_feed(&mut self, asset_id: &str) -> Result<(), FinancialError>

Simulate fetching data from a registered price feed for asset_id and populate the manager’s price-history cache. If the feed carries cached_prices, those are used directly; otherwise a deterministic series (seeded from feed_id, so the same feed always yields the same history) is generated — there is no real network in this scaffold. Returns DataError when no feed is registered for the asset.

pub fn apply_to_asset(&self, asset: &mut Asset)

Copy the manager’s cached price history for asset.asset_id onto the asset’s price_history, and refresh current_price/market_value from the last price. No-op when no history is cached for the asset.

pub fn market_data(&self) -> &MarketData

pub fn market_data_mut(&mut self) -> &mut MarketData
