std::future_error(3cxx)

💅 std::future_error — the manual page, but make it make sense

okay so bestie, welcome to the std::future_error(3cxx) page (that's the manual name right there, iykyk) — let's get into it 🫶

---

✨ NAME ✨

std::future_error — the exception type that futures throw at you. literally that's the whole vibe check, she's an exception, she gets thrown by futures 💖

---

🌸 SYNOPSIS 🌸

#include <future>

Inherits std::logic_error. no cap, that's her whole family tree 🧚

🎀 Public Member Functions

• future_error (future_errc __errc) — the constructor, takes a future_errc and gets to work
• const error_code & code () const noexcept — hands you back the error_code, noexcept so chill
• virtual const char * what () const noexcept — the iconic description getter, virtual + noexcept ✨

🦋 Friends

• void __throw_future_error (int) — yes she has a friend, and yes it returns void and takes an int

---

💜 Detailed Description 💜

Okay so: this is the exception type thrown by futures. That's her entire job. She's giving main character energy in the <future> header and honestly? obsessed 🌈

⭐ Since

C++11 — she's been iconic since C++11, periodt 💅

👑 Member Function Documentation 👑

🍓 virtual const char * std::future_error::what () const [virtual], [noexcept]

Returns a C-style character string describing the general cause of the current error. and like, it's the same string that got passed to the ctor (future_error(future_errc __errc)), so no surprises, fr fr 🎀

Reimplemented from std::logic_error — she's doing her own version of the family classic 💖

🌟 Author 🌟

Generated automatically by Doxygen for libstdc++ from the source code. not a human, not a vibe, just Doxygen doing its thing 😭

ngl bestie the whole point is: future throws std::future_error when something goes sideways, you can grab the code(), and what() gives you the cute little C-style string. that's it. that's the page. 💀

okay that's the whole page, hope this slayed for you 🫶 this was std::future_error(3cxx) from libstdc++ — mwah, go catch those exceptions bestie 💜🎀✨
