STRUCT CRYPTO_ACOMP(9)

💅 struct crypto_acomp(9) — a Kernel API Manual moment 🎀

okay so bestie, welcome to struct crypto_acomp, straight out of the Kernel API Manual ✨ this is the whole vibe of user-instantiated objects that encapsulate algorithms and core processing logic — like, the object itself is lowkey the main character and it's holding the algorithm and the processing logic together 🫶

🌸 NAME 🌸

struct crypto_acomp — user-instantiated objects which encapsulate algorithms and core processing logic 💫

✨ SYNOPSIS ✨

struct crypto_acomp {
    int (*compress)(struct acomp_req *req);
    int (*decompress)(struct acomp_req *req);
    unsigned int reqsize;
    struct crypto_tfm base;
 };

no cap, that's the whole shape of it 🦋

🎀 Members 🎀

• compress — this function performs a compress operation 🔥 it's giving "do the thing"
• decompress — this function performs a de-compress operation 💜 the reverse vibe, iconic
• reqsize — context size for (de)compression requests 📏 know your size, bestie
• base — common crypto API algorithm data structure 🧚 the foundation everything sits on

⚠️ yes, acomp_request_alloc_extra(9) really does show up twice in there — that's not me being messy, that's canon 💀
