### Async Client
```rust
use cbpro::client::{PublicClient, SANDBOX_URL};

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = PublicClient::new(SANDBOX_URL);
    let products = client.get_products().json().await?;
    println!("{}", serde_json::to_string_pretty(&products).unwrap());
    Ok(())
}
```

### Async Pagination
```rust
use cbpro::client::{PublicClient, SANDBOX_URL};
use futures::TryStreamExt;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let client = PublicClient::new(SANDBOX_URL);
    let mut pages = client.get_trades("BTC-USD").paginate()?;

    while let Some(json) = pages.try_next().await? {
        println!("{}", serde_json::to_string_pretty(&json).unwrap());
        tokio_timer::delay_for(core::time::Duration::new(1, 0)).await;
    }
    Ok(())
}
```

### Async Websocket
```rust
use cbpro::websocket::{Channels, WebSocketFeed, SANDBOX_FEED_URL};
use futures::TryStreamExt;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    let mut feed = WebSocketFeed::connect(SANDBOX_FEED_URL).await?;
    feed.subscribe(&["BTC-USD"], &[Channels::LEVEL2]).await?;

    while let Some(value) = feed.try_next().await? {
        println!("{}", serde_json::to_string_pretty(&value).unwrap());
    }
    Ok(())
}
```
