Low-latency market data systems often memcpy structs directly into network packets to minimize serialization overhead. This optimization is only safe for "trivially serializable" types—those without complex constructors, destructors, or virtual functions. A compile-time type trait can enforce this safety, preventing accidental serialization of incompatible types. Task Implement the C++ struct template IsTriviallySerializable<T>. This template must expose a static constexpr bool value that is tr
