Using std::apply on std::expected in C++23
Streamlining Error Handling in C++23
Effectively handling mistakes and managing return values is essential in today’s C++ development. The typical method of working with functions that return {std::expected} types includes a lot of checks and error handling code, which can complicate the logic and make the code more difficult to maintain.
This paper investigates the use of a more sophisticated and general method to simplify error management. In order to reduce boilerplate code and improve readability, we’ll investigate constructing a `magic_apply` method that aggregates the results of many {std::expected} values and passes them to another function.
Effective Error Management Using Variable Templates
The std::expected type is used in the scripts to ease error handling in C++23. The main goal is to develop a generic function called magic_apply that can transmit the output of several std::expected values to another function. By doing this, the tedious error-checking that is usually necessary when working with many std::expected values is reduced. magic_apply is quite…
