Implementations

impl CartItem

pub fn calculate_total( quantity: i32, unit_price: Decimal, discount: Decimal, tax: Decimal, ) -> Decimal

Calculate a line item’s money total, rounded to the currency minor unit (2 dp) so the stored/returned line total is a real money amount rather than a sub-cent value like 9.999. This matches the Postgres cart_items.total DECIMAL(12,2) column (which coerces to 2 dp) and the order pipeline’s OrderItem::calculate_total.

pub fn recalculate(&mut self)

Recalculate this item’s total
