woocommerce-subscriptions/src/Internal

The internal namespace

• All the code in this directory (and hence in the Automattic\WooCommerce_Subscriptions\Internal namespace) is internal WooCommerce Subscriptions infrastructure code.
• Our internal code can change at any time (there are zero guarantees of backwards compatibility), and so the classes and methods you see here should be avoided by extension developers.
• This guidance applies to all the code entities in this namespace, even those not having an @internal annotation.
