What it does
This interface defines a contract for filtering shopping cart request data in Magento 2.
Developers implement this interface to create filters that sanitize or modify cart-related parameters before processing, such as removing sensitive data or validating product options.
It's typically used in a composite pattern to chain multiple filters together for comprehensive data sanitization.
