Null as Optional Has Pattern. The last pattern is where most people start when it comes to protobuf. Every field in a message type that is a non-primitive generates a "has" method that returns a boolean.This method returns true if the value "has been set".We can utilize this feature to see when a consumer "has set a value".

When the protobuf compiler (protoc) compiles this message definition, it creates the code in the language of your choice (Java in our example). This generated code contains classes for defined messages, together with message and field descriptors. Descriptors contain all the information needed to encode and decode a message into its binary format.

protostructure is a Go library for encoding and decoding a struct type over the wire. This library is useful when you want to send arbitrary structures over protocol buffers for behavior such as configuration decoding (encodingjson, etc.), validation (using packages that use tags), etc. This works because we can reconstruct the struct type.

Protocol buffers, or Protobuf, is a binary format created by Google to serialize data between different services. Google made this protocol open source and now it provides support, out of the box, to the most common languages, like JavaScript, Java, C, Ruby and others. On Stack Overflow, for example, you will find roughly 1.500 questions.
