🔍 Rust Azure CLI Wrapper - Read-Only Cosmos DB

🎯 About

This library provides a safe, read-only interface to Azure Cosmos DB via the Azure CLI. It's designed for exploration, monitoring, and data discovery without the risk of accidental modifications.

✨ Key Features

• 🔒 Read-Only Design - Zero risk of accidental resource changes
• 📊 Type-Safe Models - All Azure responses as Rust structs
• 🧭 Cosmos DB Focused - SQL API, MongoDB, keys, throughput
• ⚡ Async/Await - Modern async Rust with Tokio
• 🌍 Multi-Subscription - Work across Azure subscriptions
• 📄 JSON Serializable - Easy integration with other tools

🚀 Quick Start

Prerequisites

• Azure CLI installed and authenticated (az login)
• Rust 1.70+

Basic Usage

use rust_az_wrapper::AzureClient;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = AzureClient::new()?;
    
    // Verify Azure CLI authentication
    client.verify_authentication().await?;
    
    // Explore your Cosmos DB accounts
    let accounts = client.list_cosmos_accounts(None).await?;
    
    for account in accounts {
        println!("🌍 Account: {} ({})", account.name, account.location);
        
        // Get account details
        let keys = client.list_cosmos_keys(&account.name, &account.resource_group).await?;
        println!("🔑 Has keys: Yes");
        
        // List databases
        let databases = client.list_sql_databases(&account.name, &account.resource_group).await?;
        println!("📚 Databases: {}", databases.len());
        
        for db in databases {
            // List containers in each database
            let containers = client.list_sql_containers(
                &account.name, 
                &account.resource_group, 
                &db.name
            ).await?;
            println!("  📦 {}: {} containers", db.name, containers.len());
        }
    }
    
    Ok(())
}

🛡️ Safety by Design

This library is intentionally read-only. It provides no methods to:

• Create resources
• Modify existing resources
• Delete resources
• Change configurations
• Regenerate keys

This makes it perfect for:

• 🔍 Discovery - Explore your Azure environment safely

• 📊 Monitoring - Build dashboards and reports

• 🧾 Inventory - Catalog your Cosmos DB resources

• 🔄 Integration - Feed data to other systems
