💖 std::experimental::packaged_task(libraryfundamentalsTS) 💖

okay so bestie, this is the std::experi...damentalsTS)(3) page from the C++ Standard Libary, and we are literally here for std::experimental::packaged_task. it’s giving experimental-TS main character energy, and we’re gonna keep every detail, no cap. 🫶

🌸 NAME 🌸

std::experimental::packaged_task(libraryfundamentalsTS) — std::experimental::packaged_task(libraryfundamentalsTS)

✨ Synopsis ✨

the whole synopsis vibe is right here, bestie:

Defined in header <experimental/future>
template< class > class packaged_task; //not defined (1) (library
fundamentals TS)
template< class R, class ...Args >                   (2) (library
fundamentals TS)
class packaged_task<R(Args...)>;

so std::experimental::fundamentals_v1::packaged_task (and std::experimental::fundamentals_v2::packaged_task) is a modified version of std::packaged_task provided by the library fundamentals TS with support for type-erased allocators. literally the whole plot. 💅

🎀 Member types 🎀

• allocator_type — definition: std::experimental::erased_type ✨

💅 Member functions 💅

• constructor — constructs the task object (public member function)
• get_memory_resource — retrieves a pointer to the memory resource used by this object to allocate memory (public member function)

🔁 Non-member function 🔁

• std::experimental::swap(std::experimental::packaged_task) — specializes the swap algorithm (function template)

🧚 Helper classes 🧚

• std::uses_allocator<std::experimental::packaged_task> — specializes the std::uses_allocator type trait (class template specialization)

👑 Members identical to std::packaged_task 👑

these are the members that are identical to std::packaged_task, and yes, we are listing every single one. periodt. 💜

🌈 Member functions 🌈

• destructor — destructs the task object (public member function of std::packaged_task<R(Args...)>)
• operator= — moves the task object (public member function of std::packaged_task<R(Args...)>)
• valid — checks if the task object has a valid function (public member function of std::packaged_task<R(Args...)>)
• swap — swaps two task objects (public member function of std::packaged_task<R(Args...)>)

🦋 Getting the result 🦋

• get_future — returns a std::future associated with the promised result (public member function of std::packaged_task<R(Args...)>)

🔥 Execution 🔥

• operator() — executes the function (public member function of std::packaged_task<R(Args...)>)
• make_ready_at_thread_exit — executes the function ensuring that the result is ready only once the current thread exits (public member function of std::packaged_task<R(Args...)>)
• reset — resets the state abandoning any stored results of previous executions (public member function of std::packaged_task<R(Args...)>)
