Struct commodity::exchange_rate::ExchangeRate

pub struct ExchangeRate {
    pub date: Option<NaiveDate>,
    pub obtained_datetime: Option<DateTime<Utc>>,
    pub base: Option<CommodityTypeID>,
    pub rates: BTreeMap<CommodityTypeID, Decimal>,
}

Represents the exchange rate between Commoditys with different CommodityTypes.

Fields

date: Option<NaiveDate>

The datetime that this exchange rate represents

obtained_datetime: Option<DateTime<Utc>>

The datetime that this exchange rate was obtained.

base: Option<CommodityTypeID>

The id of the base commodity type for the exchange rate

rates: BTreeMap<CommodityTypeID, Decimal>

Maps commodity type ids, to the conversion rate from that CommodityType to the base CommodityType.
