PurchaseLogic

```
public interface PurchaseLogic

                    
```
Interface for handling in-app purchases and restorations directly by the application rather than by RevenueCat. These suspend methods are called by a RevenueCat Paywall in order to execute you app's custom purchase/restore code. These functions are only called when Purchases.purchasesAreCompletedBy is set to MY_APP.
If you prefer to implement custom purchase and restore logic with completion handlers, please implement PurchaseLogicWithCallback.
