XOffsetDatastructure

Introduction

XOffsetDatastructure is a serialization library designed to reduce or even eliminate the performance consumption of serialization and deserialization by utilizing zero-encoding and zero-decoding. It is also a collection of high-performance data structures designed for efficient read and in-place/non-in-place write, with performance comparable to STL.

Release Branches

This repository maintains two parallel implementations:

release/v2.0-practical - Recommended

• Reflection: Uses Boost.PFR for compile-time reflection
• Compatibility: C++20 and above
• Stability: Production-ready, thoroughly tested
• Use Case: Recommended for production environments

release/v2.0-cpp26 - Experimental

• Reflection: Uses C++26 native reflection (std::meta)
• Compatibility: Requires C++26 (experimental compiler support)
• Stability: Experimental, cutting-edge technology
• Use Case: For exploring future C++ capabilities

Which version should I use?
For most users, we recommend release/v2.0-practical. It provides all features with proven stability and broad compiler support.
