Reflection in C++26: MetafunctionsSeptember 30, 2024 - 10:14 am
Reflection offers many metafunctions that run at compile time. The metafunctions are declared as consteval. consteval creates a so-called immediate function. Each invocation of an immediate function creates a compile-time constant. To say it more directly. A consteval (immediate) function is executed at compile-time. Read more about consteval and constinit in my previous post: Two […]
Reflection in C++26September 23, 2024 - 10:56 am
After the search into the breadth starts today, the search into the depth: reflection. Reflection Reflection is the ability of a program to examine, introspect, and modify its structure and behavior. Reflection in C++ is more. Here are two statements from the proposal (P2996R5). “We not only want to observe the structure of the program: […]
An Overview of C++26: ConcurrencySeptember 16, 2024 - 9:29 am
Today, I will finish my overview of C++26 and write about concurrency. There are still two library features left before I jump into the concurrency: saturation arithmetic and debugging support. Saturation Arithmetic Saturation arithmetic is a version of arithmetic in which all operations, such as addition and multiplication, are limited to a fixed range between […]
An Overview Of C++26: The Library – MathSeptember 9, 2024 - 10:18 am
The most interesting feature of the new C++26 standard library is its improved math support. std::submdspan std::submdspan is s a subspan of an existing span std::mdspan (C++23). The subspan didn’t make it into C++23 and was added with C++26. Before I continue with C++26, I must make a short detour to C++23. hi std::mdspan A […]
An Overview of C++26: The LibrarySeptember 2, 2024 - 10:58 am
In my last post, I overviewed C++26’s core language. Today, I continue with the library. To make it short. The library does not offer such powerful features as the core language. Let me name them and give you a short example directly from the proposal. std::string and std::string_view Processing The functions around std::string and std::string_view […]
An Overview of C++26: Core LanguageAugust 26, 2024 - 8:09 am
C++26 has a lot to offer. Let me directly jump in and give you an overview. This image gives you the first idea of what’s inside or outside C++26. Writing a blog post about the future is always challenging because the design freeze of C++26 is in the first quarter of 2025. Fishing in Murky […]
