7  |             the trait `ToTokens` is not implemented for `Ipv4Addr`
8  |             required by a bound introduced by this call

10  = help: the following other types implement trait `ToTokens`:
11            &'a T
12            &'a mut T
13            Box<T>
14            Cow<'a, T>
15            Option<T>
16            Rc<T>
17            RepInterp<T>
18            String
19          and $N others
20  = note: this error originates in the macro `quote` (in Nightly builds, run with -Z macro-backtrace for more info)
