A C++11 serialization library

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.

using cereal and boost serialisation in the same program

We currently have a system that uses a lot of boost serialisation to store data. We are looking to migrate away from this, to using cereal instead. However, it is very unlikely that we will be able to completely migrate all serialised objects. At…
