XML-RPC in Rust and Python

A lazy Sunday afternoon and my interest was piqued by XML-RPC

Client

A very basic XML-RPC client wrapped in a Cloud Functions function:

main.py:

import functions_framework
import os
import xmlrpc.client


endpoint = os.get_env("ENDPOINT")

proxy = xmlrpc.client.ServerProxy(endpoint)

@functions_framework.http
def add(request):
    print(request)
    rqst = request.get_json(silent=True)

    resp = proxy.add(
        {"x":{
            "real":rqst["x"]["real"],
            "imag":rqst["x"]["imag"]
        },
        "y":{
            "real":rqst["y"]["real"],
            "imag":rqst["y"]["imag"]
        }
    })

    return resp

requirements.txt:

functions-framework==3.*

Run it:

python3 -m venv venv
source venv/bin/activate
python3 -m pip install --requirement requirements.txt

export ENDPOINT="..."

python3 main.py

Server

Forcing myself to go Rust first and there’s an (old) xml-rpc crate.
