GuestCheckoutStrategy

A strategy that determines how to deal with guest checkouts - i.e. when a customer checks out without being logged in. For example, a strategy could be used to implement business rules such as:

• No guest checkouts allowed
• No guest checkouts allowed for customers who already have an account
• No guest checkouts allowed for customers who have previously placed an order
• Allow guest checkouts, but create a new Customer entity if the email address is already in use
• Allow guest checkouts, but update the existing Customer entity if the email address is already in use

interface GuestCheckoutStrategy extends InjectableStrategy {    setCustomerForOrder(        ctx: RequestContext,        order: Order,        input: CreateCustomerInput,    ):        | ErrorResultUnion<SetCustomerForOrderResult, Customer>        | Promise<ErrorResultUnion<SetCustomerForOrderResult, Customer>>;}
