🌸 Members 🌸

let's do a vibe check on every single field, one by one, because they ALL matter 🫶

  • data — area were the ringbuffer data is written 💾 (yes, "were" — that's how the original spells it, we don't edit the queen's spelling, periodt)
  • size — size of the ringbuffer 📏
  • pread — next position to read 👀
  • pwrite — next position to write ✍️
  • error — used by ringbuffer clients to indicate that an error happened 😭 like when things go wrong and the client needs to say so
  • queue — wait queue used by ringbuffer clients to indicate when buffer was filled 🚦 (she's the one who tells everyone "hey, it's full now")
  • lock — spinlock used to protect the ringbuffer 🔒 do NOT skip the lock, bestie, she's the bodyguard
