Protocol Buffers in Elixir

Short summary

Protocol Buffers is a binary serialization format from Google designed for efficient data transmission—faster and more compact than JSON's text format. This tutorial demonstrates how to set up and use protobuf in Elixir, including defining custom enums and message structures, compiling them with protoc, and encoding/decoding data. Walk through a complete example with a rock-paper-scissors game.

• •Protobuf offers binary serialization with better performance and size efficiency compared to JSON
• •Tutorial covers installation, syntax, and Elixir code generation using the protoc compiler
• •Practical example uses rock-paper-scissors game to demonstrate message encoding and struct creation
