we can start by trying out asio's new asio::stream_file[1] and
asio::random_access_file[2] classes based on io_uring. both classes
can be constructed with an existing file descriptor using the
'native_handle_type' overload
now that's encouraging
the synchronous case probably won't be that simple, since we won't
have an asio::io_context to construct the asio::stream_file with. we
might just fall back to the read system call there
what is the synchronous case? normally sync can be implemented on async?
