error[E0599]: the method `quote_into_iter` exists for struct `Ipv4Addr`, but its trait bounds were not satisfied

   | ---------------
   | |
   | method `quote_into_iter` not found for this struct
   | doesn't satisfy `Ipv4Addr: Iterator`
   | doesn't satisfy `Ipv4Addr: ToTokens`
   | doesn't satisfy `Ipv4Addr: ext::RepIteratorExt`
   | doesn't satisfy `Ipv4Addr: ext::RepToTokensExt`

7  |     let _ = quote! { #(#ip)* };
   |             ^^^^^^^^^^^^^^^^^^ method cannot be called on `Ipv4Addr` due to unsatisfied trait bounds
   |
   = note: the following trait bounds were not satisfied:
           `Ipv4Addr: Iterator`
           which is required by `Ipv4Addr: ext::RepIteratorExt`
           `&Ipv4Addr: Iterator`
           which is required by `&Ipv4Addr: ext::RepIteratorExt`
           `Ipv4Addr: ToTokens`
           which is required by `Ipv4Addr: ext::RepToTokensExt`
           `&mut Ipv4Addr: Iterator`
           which is required by `&mut Ipv4Addr: ext::RepIteratorExt`
note: the following traits must be implemented
  --> $RUST/core/src/iter/traits/iterator.rs
   |
   | pub trait Iterator {
   | ^^^^^^^^^^^^^^^^^^
   |
  ::: src/to_tokens.rs
   |
   | pub trait ToTokens {
   | ^^^^^^^^^^^^^^^^^^
   = note: this error originates in the macro `$crate::quote_bind_into_iter` which comes from the expansion of the macro `quote` (in Nightly builds, run with -Z macro-backtrace for more info)
