C++ State Machine benchmarked — switch/case vs GoF unique_ptr vs C++23 variant/visit

C++ State Machine, Three Ways: Switch/Case, GoF unique_ptr, and C++23 Variant — Benchmarked

Three implementations of the same aircraft lifecycle FSM — a switch/case flat machine, the classic GoF State pattern with unique_ptr, and a C++23 compile-time variant/visit design — compiled with GCC 14 at -O2 -std=c++23, measured with nanobench, and linked to four live Godbolt sessions. The headline numbers: for a full seven-event mission cycle, the variant approach is 6× faster than OOP and switch/case is essentially free (the optimizer evaluates the constant-input trace at compile time). On the steady-state telemetry hot path, switch runs at 0.56 ns/event, variant at 1.07 ns/event, OOP at 1.20 ns/event. The culprit is not virtual dispatch — it is heap allocation. A follow-up section adds get_if chains and the [[likely]] attribute: on single-variant dispatch all four strategies land within 0.11 ns.

behavior-tree-lite -- C++23 Header-Only Behavior Tree Library

Header-only C++23 behavior tree with compile-time DSL, zero heap allocations, and sub-nanosecond node dispatch. 10x smaller binary than BehaviorTree.CPP.

l2-hybrid-protocol -- Low-Latency Layer 2 Protocol for Drone Telemetry

High-performance Layer 2 raw socket networking library for Linux. Bypasses the kernel transport and network layers for deterministic latency in real-time UAV telemetry.

strong-types -- Compile-Time Type Safety for C++ Primitives

Zero-dependency C++23 strong type library with SI units, dimensional analysis, quantity points, and safe integer math. Prevents unit and coordinate mix-ups at compile time.
