Analyze, parse and decode Protocol Buffer files
Protocol Buffers (protobuf) is Google's language-neutral data serialization format:
.proto files define message structures with typed fields and unique field numbers
Binary format is much smaller than JSON/XML - ideal for network communication
Generate code for Java, Python, C++, Go, and many other languages
Field number + wire type + value encoding allows forward/backward compatibility
Encode, decode, measure sizes, and transform common formats.
