Add Rust Client Examples for AutoMQ

[johnluoyx]

Feature Request: Rust Client Examples

Description

We would like to request the addition of Rust client examples to the client-examples directory, similar to the existing Java, C++, Go, and Python examples.

Motivation

Rust is gaining significant popularity in the systems programming community, especially for high-performance applications. Having Rust client examples would:

• Help Rust developers quickly get started with AutoMQ
• Demonstrate AutoMQ's performance capabilities in a systems programming language
• Complete the language coverage for major programming languages
• Provide examples for the growing Rust ecosystem in data streaming applications

Proposed Structure

Following the pattern of existing client examples, the Rust implementation should include:

client-examples/rust/
├── Cargo.toml
├── Dockerfile
├── README.md
├── docker-compose.yml
├── run-examples.sh
├── logs/
└── src/
    ├── main.rs
    ├── config/
    │   └── automq_config.rs
    └── examples/
        ├── simple_message_example.rs
        └── transactional_message_example.rs

Expected Features

1. Simple Message Example: Basic producer and consumer functionality
2. Transactional Message Example: Demonstrate transactional messaging capabilities
3. AutoMQ Performance Tuning: Include AutoMQ-specific optimizations
4. Docker Support: Docker Compose setup for easy testing
5. Configuration Management: Environment variable support for flexible configuration
6. Performance Metrics: Throughput and latency measurements
7. Comprehensive Documentation: Clear setup and usage instructions

Technical Requirements

• Use rdkafka crate (Rust Kafka client)
• Follow Rust best practices and idioms
• Include proper error handling
• Support async/await patterns
• Provide both blocking and non-blocking examples
• Include unit tests

Dependencies

• rdkafka - Kafka client library
• tokio - Async runtime
• serde - Serialization framework
• clap - Command line argument parsing
• env_logger - Logging

Reference

Please refer to existing client examples for consistency:

• Java Examples
• C++ Examples
• Go Examples

Additional Notes

• Ensure compatibility with both AutoMQ Open Source and AutoMQ Cloud Service
• Include examples for both single-node and cluster configurations
• Provide clear migration guides from other Kafka Rust clients

This addition would greatly benefit the Rust community and showcase AutoMQ's versatility across different programming ecosystems.
