Placeholders and Extended Character SetOctober 28, 2024 - 10:19 am
Placeholders are a nice way to highlight variables that are no longer needed. Additionally, the character set of C++26 will be extended. Placeholders Structured bindings are a C++17 feature that allows you to bind multiple variables to the elements of a structured object. The following program demonstrates using tuples and structured bindings to return and […]
Contracts in C++26October 21, 2024 - 9:54 am
Contracts allow you to specify preconditions, postconditions, and invariants for functions. Contracts should already be part of C++20 but were removed in the standard meeting in Cologne. Here is what Herb Sutter said about contracts on Sutter’s Mill: “contracts is the most impactful feature of C++20 so far, and arguably the most impactful feature we […]
Reflection in C++26: Determine the LayoutOctober 14, 2024 - 9:42 am
Thanks to reflection, you can determine the layout of types. My examples are based on the reflection proposal P2996R5. Class Layout The following program determines the class layout of a few members. // classLayout.cpp #include <experimental/meta> #include <iostream> #include <utility> #include <vector> #include <array> struct member_descriptor { std::size_t offset; std::size_t size; bool operator==(member_descriptor const&) const […]
Reflection in C++26: Metafunctions for Enums and ClassesOctober 7, 2024 - 1:53 pm
Today, I continue my journey through reflection in C++26 and play with enums and classes. The names of the metafunctions to access an Enum or a Class member are often identical. Access the Members of an Enum The following program is based on one by Daveed Vandevoorde. Daveed is one of the fathers of reflection, […]
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: […]
