Crate use_money 

use-money

Money primitives pairing amounts and currencies for RustUse finance crates.

use-money combines a scaled integer Amount with a validated CurrencyCode and provides checked arithmetic only when currencies match.

Example

use use_amount::Amount;
use use_currency::CurrencyCode;
use use_money::Money;

let usd = CurrencyCode::new("USD")?;
let left = Money::new(Amount::from_minor_units(10_000, 2)?, usd.clone());
let right = Money::new(Amount::from_minor_units(2_500, 2)?, usd);

assert_eq!(left.checked_sub(&right)?.amount().minor_units(), 7_500);
