    // Create configuration
    let config = Config::new()
        .with_api_key("your-api-key")
        .with_base_url("https://api.lighter.xyz")?;

    // Initialize client with private key for trading
    let client = LighterClient::new(config, "your-private-key")?;
    
    // Get account info
    let account = client.account().get_account().await?;
    println!("Account: {:?}", account);
    
    // Get market data
    let ticker = client.market_data().get_ticker("BTC-USDC").await?;

### Migration Comparison: Python vs. Rust SDK

Source: https://github.com/yongkangc/lighter-rust/blob/master/docs/IntegrationGuide.md

Compares the initialization and order creation process between the Python and Rust SDKs. Highlights key differences such as async/await, error handling, type safety, memory management, and performance.

```Python
from lighter import LighterClient

client = LighterClient(api_key="key", private_key="0x...")
account = client.get_account()
order = client.create_order(
    symbol="BTC-USDC",
    side="buy",
    order_type="limit",
    quantity="0.1",
    price="45000"
)
```

```Rust
use lighter_rust::{LighterClient, Config, Side, OrderType};

let config = Config::new().with_api_key("key");
let client = LighterClient::new(config, "0x...")?;
let account = client.account().get_account().await?;
let order = client.orders().create_order(
    "BTC-USDC",
    Side::Buy,
    OrderType::Limit,
    "0.1",
    Some("45000"),
    None,
    None,
