FluxParse

A zero-allocation, fragment-aware, inline C++20 protocol parser.

FluxParse provides a deterministic, stack-based finite state machine for parsing fragmented byte streams. It operates entirely on std::span without heap allocation, making it suitable for embedded systems, high-frequency trading, and real-time networking.

Key Features

• Zero Allocation: No malloc/new after static initialization.
• Fragment-Aware: Designed to handle fragmented network data streams.
• Modern C++: Requires C++20 minimum.

Requirements

• GCC 12+
• Clang 15+
• MSVC 19.35+
