💖 Members 💖

okay now the fun part, let's go field by field, no skipping, we don't do that here 👑

• list — entry in the display list list of bodies. literally just her spot in the lineup 💫
• free — entry in the pool free body list. this is where she chills when she's not in use 🛋️
• refcnt — reference tracking for the body. the way that refcount is holding it DOWN, counting every single reference 😭
• pool — pool to which this body belongs. her home base, her origin story, her group chat 🏠
• entries — array of entries. the actual content, the main character energy of this struct fr fr 🔥
• dma — DMA address of the entries. where the entries live in DMA land 🗺️
• size — size of the DMA memory in bytes. yes bestie, bytes, we don't do vague here 📏
• num_entries — number of stored entries. how many she's actually holding rn 💅
• max_entries — number of entries available. the vibes ceiling, the capacity, the limit before things get awkward 🚧
