Struct Purchase 

pub struct Purchase { /* private fields */ }

A one-time cost: buying quantity units at unit_price each, optionally on a given date. A Resource can have several over its life (an initial buy, later resupply at a new price). Built with Purchase::builder

Example

use planter_core::{resources::Purchase, money::{Money, Currency}};

let purchase = Purchase::builder()
    .quantity(5)
    .unit_price(Money::from_minor_units(150, Currency::EUR))
    .build();
assert_eq!(purchase.total(), Money::from_minor_units(750, Currency::EUR));
