use rust_helia::create_helia;
use helia_unixfs::UnixFS;

#[tokio::main]
async fn main() -> Result<(), Box<dyn std::error::Error>> {
    // Create Helia instance
    let helia = create_helia().await?;
    let fs = UnixFS::new(helia);
    
    // Store content
    let cid = fs.add_bytes(b"Hello, IPFS!").await?;
    println!("Stored at: {}", cid);
    
    // Retrieve content
    let data = fs.cat(&cid).await?;
    println!("Retrieved: {}", String::from_utf8_lossy(&data));
    
    Ok(())
}
