- Mirror Bridge simplifies creating Python bindings for C++ code without manual boilerplate.
- It uses C++26 reflection to automatically discover classes, methods, and fields.
- Example: A Vec3 class in C++ can be exposed to Python with a single command.
- Performance benchmarks show significant speedups when moving hot loops to C++.
- Python's overhead for trivial operations can dominate, making C++ more efficient for intensive tasks.
- C++26 reflection allows compile-time inspection of types, enabling automatic binding generation.
- Traditional methods like pybind11 require manual listing of each method and attribute.
- Mirror Bridge is ideal for optimizing critical sections while keeping the rest of the codebase in Python.
- The tool is available via GitHub and includes a Docker setup for easy experimentation.
