Cereal

As a header-only library with no external dependencies, cereal can be dropped into any C++ project instantly, simplifying integration and deployment as highlighted in the README's quick installation steps.

cereal supports binary, XML, and JSON serialization, providing flexibility for different use cases from compact storage to human-readable configs, directly mentioned in its key features.

Built-in serialization for common C++ standard library types like std::unordered_map and std::shared_ptr reduces boilerplate code, as shown in the provided code example.

Adding serialization for custom types is done via simple template functions, such as the serialize method in MyRecord, making it straightforward to adapt to user-defined data structures.
