[go-nuts] net/netip and UDP servers

[Juliusz Chroboczek]

I'm writing a simple UDP server, and I'm trying to use the new net/netip
data types.  My main loop starts as follows:

    for {
        n, a, err := sock.ReadFrom(buf)
        if err != nil {
            log.Printf("ReadFrom: %v", err)
            time.Sleep(100 * time.Millisecond)
            continue
        }
        aa, ok := a.(*net.UDPAddr)
        if !ok {
            log.Println("not a UDP address (this shouldn't happen)")
            continue
        }
        ip, ok := netip.AddrFromSlice(aa.IP)
        if !ok {
            log.Println("AddrFromSlice not ok")
            continue
        }
        ip = ip.Unmap()
        addr := netip.AddrPortFrom(ip, uint16(aa.Port))

That seems extremely verbose.  Am I doing something wrong?
