Optimize reaction memory without heap allocation#19
Draft
Conversation
This commit introduces Small Buffer Optimization (SBO) to the Reaction framework. SBO allows small, trivially destructible types to be stored directly within the reactive node, avoiding heap allocations and improving performance. Key changes include: - **`OptimizedResource<Type>`**: A new resource implementation that uses SBO for eligible types. - **`ResourceImpl<Type>`**: A type alias in `resource_selector.h` that conditionally uses `OptimizedResource` or the standard `Resource` based on the `REACTION_ENABLE_SBO` macro. - **SBO Criteria**: Defined by size (<= 32 bytes), trivial destructibility, and standard alignment. - **Benchmarks**: Added `bench_sbo.cpp` to compare performance of standard vs. SBO implementations. - **Unit Tests**: Added `test_sbo_optimization.cpp` to verify SBO functionality. - **Documentation**: Added `docs/SBO_OPTIMIZATION.md` and `SMALL_MEMORY_OPTIMIZATION_SUMMARY.md` to explain SBO. - **Example**: Added `example/sbo_example.cpp` to demonstrate SBO usage. SBO is disabled by default to ensure backward compatibility. It can be enabled by defining `REACTION_ENABLE_SBO` before including Reaction headers.
