fn price_markets(
    model: &Model,
    solution: &Solution<'_>,
    year: u32,
    markets: &[(CommodityID, RegionID)],
    shadow_prices: &CommodityPrices,
    annual_activities: &mut Option<HashMap<AssetRef, Activity>>,

)

Calculate prices for a collection of independent markets and insert them into result.

result serves as both the source of input prices (prices of input commodities from upstream markets already computed) and the destination for newly computed prices.

Arguments

• model - The model
• solution - Solution to dispatch optimisation
• year - The year for which prices are being calculated
• markets - The markets to calculate prices for
• shadow_prices - Shadow prices for all commodities
• annual_activities - Optional map of annual activities for all assets, used for full cost pricing. If not provided, it will be calculated on demand if at least one market uses full cost pricing.
