WebFlatBuffers is an efficient cross platform serialization library for C++, C#, C, Go, Java, JavaScript, PHP, and Python. It was originally created at Google for game development and other performance-critical applications. ^ Kenton Varda (2014-06-17). "Cap'n Proto, FlatBuffers, and SBE". Retrieved 2024-06-15. WebFlatbuf has 2 apis in c++, the classical one, with its create calls, and the object one, where a plain struct is created by the code generator, which can also be serialised, albeit slower than with the non object api. When used in c++, flatbuf allows a great deal of flexibility, down to specifying your own pointer types for the auto-generated code.
