Use when building Linux servers with liburing, batching SQEs, multi-shot operations, provided buffer rings, registered files and buffers, or zero-copy send. Not for packet I/O: use af-xdp.

# io_uring

## Contract

| Field | Bound contract |
|---|---|
| Trigger | Building or tuning Linux async I/O with io_uring: the SQE/CQE model, liburing usage, multi-shot accept or recv, provided buffer rings, fixed files and buffers, zero-copy send, tokio-uring, or the io_uring versus epoll decision. |
| Authority | Read-only. Writes nothing. Chat output only. No remote mutation. |
| Side effect | Returns setup code, ring lifecycle rules, and a comparison verdict. No source files are modified. |
| Done | The liburing example, the multi-shot and buffer-ring patterns, the zero-copy rule, and the epoll comparison verdict are delivered. |

## Inputs

1. Workload shape (required): network or disk, operation mix, and connection count.
