WalkthroughThe recent updates enhance the structure and maintainability of smart contracts by transitioning from direct state variable access to a defined storage pattern utilizing structs. This change promotes better encapsulation, aligns with best practices for proxy patterns, and improves gas efficiency. Key constants governing implementation slots were also updated, ensuring compatibility with current standards while maintaining the essential functionality of the contracts. Changes

10-15: Adopt structured storage for better state management.The introduction of the
NonUpgradeableMockStoragestruct and the use of a specific storage slot enhance state management. This approach aligns with best practices for proxy patterns and improves gas efficiency.
18-19: Ensure correct access to structured storage.The
counterfunction correctly accesses thecountervariable through the storage struct. This approach ensures consistent state management.
23-24: Ensure correct state modification through structured storage.The
incrementfunction correctly modifies thecountervariable through the storage struct. This approach ensures consistent state management.
30-38: Correctly retrieve storage pointer using inline assembly.The
_getNonUpgradeableMockStoragefunction correctly retrieves the storage pointer using inline assembly. This approach ensures that the storage slot is correctly accessed.
42-49: Adopt structured storage for better state management.The introduction of the
UUPSUpgradeableMockStoragestruct and the use of a specific storage slot enhance state management. This approach aligns with best practices for proxy patterns and improves gas efficiency.
