### Create Avatar Video with Heygen Rust SDK

Source: https://github.com/onlycoiners/heygen_rust/blob/main/README.md

Demonstrates how to create an AI-generated avatar video using the Heygen Rust SDK. Requires an API key and specifies video inputs including character, voice, and dimensions.

```rust
use heygen::HeyGenBot;
use serde_json::json;

#[tokio::main]
async fn main() {
    // Create a new HeyGen client
    let client = HeyGenBot::new("your-api-key".to_string(), Some("https://api.heygen.com/v2/")).unwrap();

    // Create a video using an avatar
    let payload = json!({
        "video_inputs": [{
            "character": {
                "type": "avatar",
                "avatar_id": "Angela-inTshirt-20200820",
                "avatar_style": "normal"
            },
            "voice": {
                "type": "text",
                "input_text": "Hello from the HeyGen Rust SDK!",
                "voice_id": "1bd001e7e50f421d891986aad5158bc8",
                "speed": 1.1
            }
        }],
        "dimension": {
            "width": 1280,
            "height": 720
        }
    });

    // Generate the video
    match client.create_avatar_video(payload).await {
        Ok(response) => {
            if let Some(data) = response.data {
                println!("Video generated successfully! ID: {}", data.video_id);
            }
        }
        Err(e) => eprintln!("Error generating video: {}", e),
    }
}
```
