Minimal Logging Framework in C++20
summary
A compact C++20 logger is built: about 200 lines that record an 8‑byte high‑resolution timestamp (8 bytes timestamp), an instruction pointer, a second instruction pointer to encode argument types, and binary arguments into a circular fixed-capacity buffer allocated before the hot path. Runtime formatting is avoided, offline decoding uses a symbol archive to map addresses back to file/line/types. Unit tests validate timing and decoding; it reduces I/O and space dramatically but requires care with inlining, ASLR/load addresses and added bookkeeping.
