Learn to develop an embedded domain-specific language (DSL) for parsing binary data formats using C++23 template metaprogramming techniques in this 46-minute conference talk from Meeting C++ 2025. Explore how to create binary format parsers without handwritten boilerplate code or code generators, addressing common C++ challenges like the absence of reflection, padding, alignment, variances, and validation concerns. Walk through a simplified implementation that can parse binary data from files, networks, or buffers, and compare this approach with existing solutions in the C++ ecosystem. Discover practical techniques for leveraging C++23's advanced template metaprogramming capabilities to create clean, efficient binary parsing solutions while examining real-world implementation details and design considerations.
