Type Alias CommodityBalanceKeys 

pub type CommodityBalanceKeys = KeysWithOffset<(CommodityID, RegionID, TimeSliceSelection)>;

Indicates the commodity ID and time slice selection covered by each commodity balance constraint

Aliased Type

pub struct CommodityBalanceKeys {
    offset: usize,
    keys: Vec<(CommodityID, RegionID, TimeSliceSelection)>,
}

Fields

offset: usize

Row offset in the solver’s row ordering corresponding to the first key in keys.

This offset is used to index into the solver duals vector when mapping dual values back to the stored keys.

keys: Vec<(CommodityID, RegionID, TimeSliceSelection)>

Keys for each constraint row. The number of keys equals the number of rows covered starting at offset.
