Enum RefundReason 

pub enum RefundReason {
    Duplicate,
    Fraudulent,
    RequestedByCustomer,
    Other(Box<str>),
}

What a merchant tells the provider the money went back for.

Not a label for the shop’s own use. Two of the five providers here have a field for it that ends up in chargeback and reconciliation reporting — Stripe’s reason, iyzico’s reason — and a fraudulent order refunded without saying so has told them nothing, and cannot tell them later.

The three named ones are the intersection: Stripe documents exactly these three, and iyzico’s four are these three plus its own OTHER. What each adapter does with them, and with RefundReason::Other, is on that adapter’s refund.

Exhaustive, for the same reason Currency is

This is a value travelling out to a provider rather than one a caller reads back, and an adapter that met a reason it had no word for would quietly send none — which is the failure this type exists to prevent. Adding a variant is a breaking change, and it forces every adapter to say what it maps to.

Variants

Duplicate

The same money was taken twice.

Fraudulent

The payment was not the cardholder’s.

RequestedByCustomer

The buyer asked for their money back.

Other(Box<str>)

Something else, in the caller’s own words.

A provider with a free-text field takes this; one with an enumeration sends its own “other” value beside it, and one with neither drops it. Which of the three a provider is, is on its refund.
