ENUM NFT_SET_EXTENSIONS(9)

💅 NAME

okay so this is the enum nft_set_extensions(9) page from the Kernel API Manual, and it's literally all about set extension type IDs 💖

enum nft_set_extensions — set extension type IDs. That's the whole vibe, bestie ✨

✨ SYNOPSIS

enum nft_set_extensions {
    NFT_SET_EXT_KEY ,
    NFT_SET_EXT_KEY_END ,
    NFT_SET_EXT_DATA ,
    NFT_SET_EXT_FLAGS ,
    NFT_SET_EXT_TIMEOUT ,
    NFT_SET_EXT_USERDATA ,
    NFT_SET_EXT_EXPRESSIONS ,
    NFT_SET_EXT_OBJREF ,
    NFT_SET_EXT_NUM

};

🎀 Constants

• NFT_SET_EXT_KEY — the element key, periodt 🔑
• NFT_SET_EXT_KEY_END — the upper-bound element key, specifically for ranges 📈
• NFT_SET_EXT_DATA — the mapping data, iykyk 🗺️
• NFT_SET_EXT_FLAGS — the element flags 🚩
• NFT_SET_EXT_TIMEOUT — the element timeout ⏳
• NFT_SET_EXT_USERDATA — the user data that's associated with the element 🙈
• NFT_SET_EXT_EXPRESSIONS — the expressions that are associated with the element 🧚
