Minimal Structured Logging for Autonomous Vehicles
summary
A fast structured logger separates metadata (file, format, type descriptors) from per-instance fields, assigns a unique ID via a static linked list pre-main, and writes tiny binary records of ID+replacement bytes so fleet logs share one metadata file. Implementation uses an anonymous struct + macro in C++17, Explanation＜＞ as the serializable payload type, ring buffers plus a background writer for batching, and C++20 NTTP/fixed_string removes the do‑while workaround; porting shows no noticeable compile‑time penalty.
