Usage​

import os
from quantumdmn import DmnEngine, ZitadelTokenProvider, FeelValue, ApiClient, Configuration

# Configuration
key_file = "path/to/service-user.json"
issuer_url = "https://auth.quantumdmn.com"

# 1. Setup Auth
auth = ZitadelTokenProvider(key_file, issuer_url, project_id_auth)

# 2. Configure Client

# 3. Initialize Engine
engine = DmnEngine(client, project_id_dmn)

# 4. Prepare Context using FeelValue for precise types

# 5. Evaluate
