std::packaged_task::valid(3)

✨ std::packaged_task::valid ✨

okay so real talk, this page comes straight out of the C++ Standard Libary manual (yes that's the manual name, we don't edit it, we respect it 💅) and it's honestly one of the shortest reads ever. it's giving "one question, one answer" energy and i'm kinda obsessed.

🌸 NAME 🌸

std::packaged_task::valid — that's it, that's the whole name. it does exactly what it says on the tin, no cap.

🎀 Synopsis 🎀

bool valid() const noexcept;  (since C++11)

so this lil member function checks whether *this has a shared state. that's the entire vibe check right there 🦋

it's been hanging out since C++11, and it's written const noexcept — i'm just reading the signature to you exactly as it appears, bestie, not adding my own lore ✨

💖 Parameters 💖

(none)

literally zero. nothing. no arguments, no surprises, she takes no notes 🙈

⭐ Return value ⭐

• true — if *this has a shared state 🔥
• false — otherwise 💀

that's the whole deal. binary queen 👑

so yeah, that's the page. iconic, brief, no filler. go check if your packaged_task actually has a shared state before you get weird with it, iykyk 🫶
