Standard Library Containers

Pack provides limited support for serializing (but not necessarily deserializing) standard library containers through concepts.

• Anything convertible to std::span can be serialized as an Array (std::vector, etc)
• Anything convertible to std::string_view can be serialized as a String (std::string, null-terminated const char *, etc)

Getting Started

As a header-only library, using Pack is as simple as including the header file in your project. CMake is necessary only for building the unit tests.

The public interface for the library is designed to be familiar for anyone who has utilized the excellent Cereal library. Usage revolves around the Packer and Unpacker classes that are constructed with some kind of c++ stream. Note that similarly to Cereal, the stream is not flushed until the destructor is called:

   std::stringstream stream(std::ios::binary | std::ios::out | std::ios::in);

   {
      pack::Packer packer(stream);
      packer.Serialize(data1, data2, ...);
   }

   // Later...
   {
      pack::Unpacker unpacker(stream);
      unpacker.Deserialize(data1, data2, ...);
   }
