std::tr2::bool_set(3)

💖 std::tr2::bool_set — Library Functions Manual 💖

okay bestie, sit down, hydrate, because today we're learning about std::tr2::bool_set, and honestly? it's giving philosopher queen. it's a boolean that woke up and chose chaos — she can be true, she can be false, she can be empty, she can be indeterminate, she's a whole multi-valued icon. 🌈✨

this page lives in section 3 of the library functions manual, iykyk. let's get into it. 🎀

✨ NAME ✨

std::tr2::bool_set — the multi-valued logic girlie herself 💅

---

🌸 SYNOPSIS 🌸

#include <bool_set>

🦋 Public Member Functions

• constexpr bool_set () — default constructor. she just exists, no thoughts, head empty (literally, that's a whole state).
• constexpr bool_set (bool __t) — constructor from bool. feed her a true or a false and she'll take it.
• bool contains (bool_set __b) const — no blurb attached to this one, she's mysterious, we respect it 🙈
• bool equals (bool_set __b) const — return true if states are equal. twin check. 💞
• bool is_emptyset () const — return true if this is empty.
• bool is_indeterminate () const — return true if this is indeterminate. the "idk her" state fr.
• bool is_singleton () const — return true if this is false or true (normal boolean). so like, the basic b*tch state, but affectionately.
• operator bool () const — conversion to bool.

🌟 Static Public Member Functions

• static bool_set emptyset ()

👑 Detailed Description 👑

bool_set

See N2136, Bool_set: multi-valued logic by Hervé Brönnimann, Guillaume Melquiond, Sylvain Pion. 📚✨

the implicit conversion to bool is slippery! 😭 I may use the new explicit conversion. This has been specialized in the language so that in contexts requiring a bool the conversion happens implicitly. Thus most objections should be eliminated.

so basically: she can slide into a bool when the context is begging for one, and that's on purpose, no cap. 🫶
