One of the things I like to do is compare how different languages solve the same problem — especially when they end up having very different approaches. It’s always educational. In this case, a bunch of us have been working hard on trying to get reflection — a really transformative language feature — into C++26. Fundamentally, reflection itself can be divided into two pieces:

Dan Brevik's blog covers a broad range of topics, including web development, programming languages, and software engineering best practices. Readers can find tutorials on front-end frameworks, back-end technologies, and principles for writing clean, maintainable code in various programming languages. Additionally, they can explore articles on software architecture, design patterns, and strategies for improving developer productivity and collaboration.

The post compares how Rust and the upcoming C++26 handle code generation and reflection. While C++26 is working on integrating reflection capabilities, Rust excels in code generation using declarative and procedural macros. Key examples include pretty-printing structs and JSON serialization, highlighting the differences in syntax and library design between the two languages. The discussion emphasizes how Rust's derive macros inject necessary implementations automatically, whereas C++ uses introspection to achieve similar results with less boilerplate code.
