ENUM NFT_SET_CLASS(9)

✨ enum nft_set_class(9) ✨

okay bestie, so this is a page from the Kernel API Manual and it's literally all about enum nft_set_class — the ✨performance class✨ enum. it's short, it's sweet, it's giving minimal icon energy 💅

---

🌸 NAME 🌸

enum nft_set_class — performance class, no cap 🏎️✨

---

🦋 SYNOPSIS 🦋

enum nft_set_class {
    NFT_SET_CLASS_O_1 ,
    NFT_SET_CLASS_O_LOG_N ,
    NFT_SET_CLASS_O_N

};

like… that's the whole thing. three constants and a dream 🎀

---

👑 Constants 👑

• NFT_SET_CLASS_O_1 — constant, O(1). the main character of complexity classes fr fr, it does not care how big your N gets 💅🔥
• NFT_SET_CLASS_O_LOG_N — logarithmic, O(log N). lowkey the sensible middle child 🌀✨
• NFT_SET_CLASS_O_N — linear, O(N). it scales with N, bestie — every element gets its moment, no skipping 🫶😭
