Order line item

Fields

id: OrderItemId

order_id: OrderId

product_id: ProductId

variant_id: Option<Uuid>

sku: String

name: String

quantity: i32

unit_price: Decimal

discount: Decimal

tax_amount: Decimal

total: Decimal

Implementations

impl OrderItem

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.

The result is rounded to MONEY_SCALE (2) decimal places so the stored line total is a real money amount and an order’s total_amount (the sum of these line totals) foots exactly to its line items. All order-creation paths on both backends route through this function so they agree to the cent.
