✨ NAME ✨

🎀 ARGUMENTS 🎀

  • rqstp — RPC transaction context. The main character context, iykyk. 🫶
  • head — context for ongoing I/O. Lowkey the headquarters for the ongoing I/O situation. ✨
  • segment — co-ordinates of remote memory to be read. It's giving "remote memory co-ordinates," periodt. 🌸

🔥 RETURN 🔥

  • 0 — the Read WR chain was constructed successfully. Slay, it worked. 💖
