With features like std::tuple, structured bindings, std::expected, and std::optional, handling multiple. Tagged with cpp, errors, handleerrors. Coroutines coroutines are special functions that can have their execution suspended and resumed

To define a coroutine, the co_return, co_await, or co_yield keywords must be present in the function's body
Unless optimized out by the compiler, their state is allocated on the heap.
The aim of this document is to help people to use modern c++ effectively By “modern c++” we mean effective use of the iso c++ standard (currently c++20, but almost all of our recommendations also apply to c++17, c++14 and c++11) In other words, what would you like your code to look like in 5 years’ time, given that you can start now? Using std::pair and std::tuple is considered bad practice because first, second, and std::get<n> don't provide any information about what is stored in that data field.
The only reason i do a copy is i hate reading markdowns from github I want something simple and plain for my own reference. A tuplet::tuple is implemented as an aggregate containing it's elements, and this ensures that it's We can return a tuple std::pair<bool, std::string>
But that makes code redundant when creating the return value , and force callers to handle the tuple (easy with structural
A compiler error results if a given type does not satisfy the concept it's bound by (i.e Tuple can also be used to return two values instead of using pair. A cheatsheet of modern c++ language and library features A cheatsheet of modern c++ language and library features.
Discover the art of c++ unpack tuple in this concise guide that simplifies extraction and manipulation of tuple elements with ease. Common lisp functions can return multiple return values in a different way If they're used in an ordinary expression, only the first value is used and the rest are ignored, but there are certain contexts that examine multiple/all of the return values (e.g Modern c++ has provided an elegant and structured way of error handling and this article shows how
