## Description

Serial is a Java library designed for high-speed object serialization and binary data processing. It converts complex objects into compact byte arrays to facilitate efficient storage and network transmission, specifically targeting environments where memory and resource efficiency are critical.

The library distinguishes itself by bypassing reflection, instead utilizing manual field mapping and generated bytecode to perform object inspection. This approach ensures a deterministic byte layout and provides type-safe buffer management, which allows for predictable data structures. To support long-term data integrity, the framework includes schema-aware versioning, enabling backward compatibility as application data structures evolve over time.

Beyond core serialization, the project provides diagnostic utilities for inspecting and validating serialized byte arrays. These tools assist in debugging the internal structure of data to resolve processing errors. The library is optimized for use in mobile environments, providing a lightweight solution for application state persistence.
