/**
 * Invoice Items represent the component lines of an <a href="https://stripe.com/docs/api/invoices">invoice</a>. An invoice item is added to an
 * invoice by creating or updating it with an <code>invoice</code> field, at which point it will be included as
 * <a href="https://stripe.com/docs/api/invoices/line_item">an invoice line item</a> within
 * <a href="https://stripe.com/docs/api/invoices/object#invoice_object-lines">invoice.lines</a>.
 *
 * Invoice Items can be created before you are ready to actually send the invoice. This can be particularly useful when combined
 * with a <a href="https://stripe.com/docs/api/subscriptions">subscription</a>. Sometimes you want to add a charge or credit to a customer, but actually charge
 * or credit the customer’s card only at the end of a regular billing cycle. This is useful for combining several charges
 * (to minimize per-transaction fees), or for having Stripe tabulate your usage-based billing totals.
 *
 * Related guides: <a href="https://stripe.com/docs/invoicing/integration">Integrate with the Invoicing API</a>, <a href="https://stripe.com/docs/billing/invoices/subscription#adding-upcoming-invoice-items">Subscription Invoices</a>.
 *
 * @property string $id Unique identifier for the object.
 * @property string $object String representing the object's type. Objects of the same type share the same value.
 * @property int $amount Amount (in the <code>currency</code> specified) of the invoice item. This should always be equal to <code>unit_amount * quantity</code>.
 * @property string $currency Three-letter <a href="https://www.iso.org/iso-4217-currency-codes.html">ISO currency code</a>, in lowercase. Must be a <a href="https://stripe.com/docs/currencies">supported currency</a>.
 * @property Customer|string $customer The ID of the customer who will be billed when this invoice item is billed.
 * @property int $date Time at which the object was created. Measured in seconds since the Unix epoch.
 * @property null|string $description An arbitrary string attached to the object. Often useful for displaying to users.
 * @property bool $discountable If true, discounts will apply to this invoice item. Always false for prorations.
 * @property null|(Discount|string)[] $discounts The discounts which apply to the invoice item. Item discounts are applied before invoice discounts. Use <code>expand[]=discounts</code> to expand each discount.
 * @property null|Invoice|string $invoice The ID of the invoice this invoice item belongs to.
 * @property bool $livemode Has the value <code>true</code> if the object exists in live mode or the value <code>false</code> if the object exists in test mode.
 * @property null|StripeObject $metadata Set of <a href="https://stripe.com/docs/api/metadata">key-value pairs</a> that you can attach to an object. This can be useful for storing additional information about the object in a structured format.
 * @property null|(object{subscription_details: null|(object{subscription: string, subscription_item?: string}&StripeObject), type: string}&StripeObject) $parent The parent that generated this invoice
 * @property (object{end: int, start: int}&StripeObject) $period
 * @property null|(object{price_details?: (object{price: string, product: string}&StripeObject), type: string, unit_amount_decimal: null|string}&StripeObject) $pricing The pricing information of the invoice item.
 * @property bool $proration Whether the invoice item was created automatically as a proration adjustment when the customer switched plans.
 * @property int $quantity Quantity of units for the invoice item. If the invoice item is a proration, the quantity of the subscription that the proration was computed for.
 * @property null|TaxRate[] $tax_rates The tax rates which apply to the invoice item. When set, the <code>default_tax_rates</code> on the invoice do not apply to this invoice item.
 * @property null|string|TestHelpers\TestClock $test_clock ID of the test clock this invoice item belongs to.
