io

IO library

first-class backend is IO_URING. everything else defers to whatever is most portable (on Windows and Mac). The URING system provides low level bindings to IO_URING.

We implement a high-level API for IO. The API is meant to be as simple as possible, while still providing a great deal of control over the primitive IO queues.

Speed is the priority.

• We will probably need a specialized vector class mapping/displaced directly to URING::IOVECs
• io-stream doesn't share or inherit structure from sb-sys:fd-stream
• io-socket doesn't share or inherit structure from sb-bsd-sockets:socket
• prioritizing UDP/datagram/framed sockets over TCP/streamed
• testing:
  • use NET/CODEC/TLV:TLV for passing simple messages from SQ->CQ
  • use IO-OP-NOP for estimating throughput and comparing implementations (rust/tokio)
