cereal is a header-only C++11 serialization library. cereal takes arbitrary data types and reversibly turns them into different representations, such as compact binary encodings, XML, or JSON. cereal was designed to be fast, light-weight, and easy to extend - it has no external dependencies and can be easily bundled with other code or used standalone.
Looking for more information on how cereal works and its documentation? Visit cereal's web page to get the latest information.
Installation and use of of cereal is fully documented on the main web page, but this is a quick and dirty version:
- Download cereal and place the headers somewhere your code can see them
- Write serialization functions for your custom types or use the built in support for the standard library cereal provides
- Use the serialization archives to load and save data
