Astarte message hub proto

This repository contains the .proto files used by the Astarte message hub as well as by any client that wishes to connect itself to the message hub.

Protobuf and gRPC versions

For each of the supported languages this repository contains also the compiled protobuf definitions contained in the .proto files. In addition the gRPC services for those .proto files are also generated. Since different languages may use different gRPC implementations and protobuf compilers here is a table with the used versions.

Language	gRPC library	gRPC library version	protoc version
Rust	tonic	v0.12.3	29.3
Python	grpc	v1.69.0	29.0
C++	grpc	Default v1.69.0	Default 29.0

N.B. For C++ the version of gRPC and protoc is user configurable through CMake options.
