Protobuf C++ library

Protobuf C++ (Protocol Buffers for C++) is a data serialization library developed by Google that simplifies the process of encoding structured data into a compact, efficient format for storage or transmission. It allows developers to define data schemas using a simple language, which then automatically generates C++ code to handle serialization (converting data into a transmittable format) and deserialization (reading data back). This makes data exchange between programs faster, smaller, and more reliable, especially in distributed systems or network communications. Overall, it streamlines managing and sharing complex data structures across different software components.
