   Code Generation in Rust vs C++26

   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.

   Rust vs. Zig – and C++ and Mojo – for Systems Programming

   At P99 CONF, a debate between Jarred Sumner, Pekka Enberg, and Glauber Costa on ThePrimeagen's Twitch stream explored the benefits and drawbacks of Rust and Zig for systems programming. Key points included Rust's memory safety and robust ecosystem, and Zig's low-level control and better interoperability with C. They also touched on Mojo's potential, particularly for machine learning, and agreed that both Rust and Zig offer significant advantages over older versions of C++.

   What’s new in C++26 (part 1)

   C++26 introduces several new language and library features, such as specifying a reason for deleting a function, using placeholder variables with no names, and allowing structured binding declarations as conditions. Additionally, static_assert messages can now be user-generated at compile time with string-like objects.

   std::array in C++ isn't slower than array in C

   The post discusses the performance of std::array in C++ compared to built-in C arrays. It examines library implementations (LLVM and GNU), assembler code, and benchmarks to show that std::array is not slower than C arrays, especially when compiler optimizations are enabled. Finally, it addresses concerns about object file sizes and highlights the benefits of using std::array over C arrays.
