Accept

Accept abstracts the underlying io_uring::opcode::Accept.

This Single-shot Accept provides the source socket address and port within the completion.

If you either don't need the source address and / or port, consider using the AcceptMulti instead.

Note: This is being migrated to implement the OpCode + OpCompletion traits similar to EpollCtl.

Submission

You can currently push single-shot Accept unsafely depending on whether the underlying TcpListener RawFd is IPv4 or IPv6:

• IPv4: UringBearer::add_accept_ipv4
• IPv6: UringBearer::add_accept_ipv6

To use it safely, user must ensure that the underlying socket is either exclusively IPv4 or IPv6 given the returned source address and structure layout is different depending on which one it is.

If someone needs UNIX sockets, please feel free to send a PR.

Completion

Accept(AcceptRec) will show up as normal through the handler API through UringBearer.

Lifetime (Manual handling)

SubmissionRecordStatus::Forget is safe given the pending Completion was Single-shot.

If the completed record is retained, this will result in memoryleak.
