Output • The output is a Data buffer. The buffer is a flat, contiguous block of data designed for storage or transmission. • As illustrated in the diagram, the data buffer is a single, uninterrupted space space used to hold data. Fanchen Su, XOffsetDatastructure, CppCon 2024 18 Data Buffer2.1.1 What Is Serialization and Deserialization • Process • The Process involves converting between structured First Category • Serialization • The output is a data buffer. • The process involves transforming the memory data structure into a data buffer. This transformation requires traversing and encoding
