STRUCT NFT_SET_BINDING(9)

💖 struct nft_set_binding(9) 💖

okay so this is a page from the Kernel API Manual, and bestie, it's literally about struct nft_set_binding. no cap. It's the nf_tables set binding struct, and we're gonna go through it together. 🫶

🎀 NAME 🎀

struct nft_set_binding — nf_tables set binding. That's the whole vibe: this struct is the nf_tables set binding, periodt. 💅

✨ SYNOPSIS ✨

okay so here's the shape, exactly:

struct nft_set_binding {
    struct list_head                list;
    const struct nft_chain          *chain;
    u32 flags;
 };

💅 Members 💅

• list — set bindings list node. literally the list node, bestie. 🎀
• chain — chain containing the rule bound to the set. In the synopsis it's a const struct nft_chain *, iykyk. 🔥
• flags — set action flags. that's the flags situation. ✨

🌸 DESCRIPTION 🌸

A set binding contains all information necessary for validation of new elements added to a bound set. That's it. That's the job. It holds all the info you need for validating new elements when they're added to a bound set. iconic, honestly. 💜
