[−][src]Struct commodity::exchange_rate::ExchangeRate
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<CurrencyCode>
The base currency for the exchange rate
rates: HashMap<CurrencyCode, Decimal>
Maps currency codes, to the conversion rate from that currency to the base currency.
Methods
impl ExchangeRate

[src]
&self,
commodity: Commodity,
target_currency: CurrencyCode
) -> Result<Commodity, ExchangeRateError>
