Struct FxRate 

pub struct FxRate {
    pub base: Currency,
    pub quote: Currency,
    pub rate: f64,
    pub timestamp: i64,
}

An FX quote between two currencies: base_currency / quote_currency = rate.

Example: EUR / USD = 1.08 means 1 EUR = 1.08 USD.

Fields

base: Currency

quote: Currency

rate: f64

timestamp: i64

Epoch timestamp of the quote in seconds or milliseconds (caller-defined convention).

Implementations

impl FxRate

pub fn new( base: impl Into<Currency>, quote: impl Into<Currency>, rate: f64, ) -> Self

pub fn convert( &self, amount: f64, from: &Currency, to: &Currency, ) -> Result<f64, FxConversionError>

Converts an amount from from currency to to currency using this FX rate.

If from == to, returns Ok(amount) without needing a valid FX quote. If missing or inverted, computes the direct or reciprocal rate.
