Killing C++ Serialization Overhead & Complexity
summary
Claims a C++20, macro‑less serializer (zpp bits) that matches or beats handwritten code in benchmarks (handwritten ~830 ms, zpp bits ~827–879 ms after tweaks) and produces tiny binaries versus multi‑megabyte libraries (examples: 2 MB vs ~43 KB). Uses memcpy/bitcast, templates, Concepts, constexpr and force inline to get the compiler to emit memcpy instead of per‑byte loops, supports freestanding/embedded operation without exceptions, offers RPC via variants and structured‑binding reflection workarounds, and is implemented and validated against protobuf/flatbuffers benchmarks.
