💖 NAME 💖

struct nvme_lba_range_type_entry — no cap, this is the LBA Range Type - Data Structure Entry, and it lives right here in the libnvme API manual, section 2, bestie 🫶

---

✨ SYNOPSIS ✨

okay so here's the whole shape of it, character for character, don't touch the padding:

struct nvme_lba_range_type_entry {
    __u8 type;
    __u8 attributes;
    __u8 rsvd2[14];
    __le64 slba;
    __le64 nlb;
    __u8 guid[16];
    __u8 rsvd48[16];
 };

like. look at those little reserved gaps. the struct said "i need space" and the spec said "say less" 💅

🎀 Members 🎀

• type — picks what Type of LBA range this baby is. it's the vibe check for the whole entry, fr fr.
• attributes — the attributes of the LBA range. all the personality traits, right here ✨
• rsvd2 — Reserved. hands off, it's not for you, it's a __u8 array of 14. leave it alone 🙈
• slba — the Starting LBA. where the range begins, __le64, little-endian bc ofc it is 🌸
• nlb — the Number of Logical Blocks. how many blocks we're counting, also __le64. iconic.
• guid — the Unique Identifier. __u8 array, 16 bytes of pure main character energy 👑
• rsvd48 — also Reserved. __u8 array, 16 bytes, also none of your business 💀

ngl, notice how there are two reserved fields — rsvd2 and rsvd48 — and they are not the same size bestie. 14 vs 16. do not confuse them. that's the whole lore.

and that's the entry! short, sweet, deeply obsessed with byte alignment 🦋
