```rust
use claudecode::api::gateway::Gateway;
use claudecode::api::models::ChatCompletionRequest;

fn main() {
    let gateway = Gateway::new("http://localhost:8080");
    
    let request = ChatCompletionRequest {
        model: "claude-2".to_string(),
        messages: vec![
            claudecode::api::models::Message {
                role: "user".to_string(),
                content: "Explain Rust's ownership model.".to_string(),
            },
        ],
        max_tokens: Some(150),
    };
    
    let response = gateway.chat_completion(request).unwrap();
    println!("Response: {:?}", response);
}
```

The above code demonstrates how to use the Claude Code API gateway in Rust. It creates a new gateway instance, constructs a chat completion request, and sends it to the gateway. The response is then printed to the console.
