Re: [Cppcms-users] What is the best practice to serialize vector of struct?

[Artyom B. <art...@ya...>]

You can provide a specialization for serialization traits like 

namespace cppcms {
 serialization_traits<std::vector<page> > {
   load(...)
   save(...)
 }
};

It is generally designed to be used with custom (not-cppcms based) serialization methods.

I woudn't say it is best practice, but it would allow you not to use the "wrapper" class.
