Rust SDK for Google Cloud now available

// This program demonstrates the new Rust SDK for Google Cloud.
// It does not compile until the SDK crate is published.
// For now, it shows how you would use the crate once available.

fn main() {
    // In a real project you would add the SDK to Cargo.toml:
    // google_cloud_sdk = "0.1"
    //
    // Then you could do something like:
    // let client = google_cloud_sdk::Client::new("path/to/key.json");
    // let buckets = client.storage().list_buckets("my-project").await?;
    // println!("Buckets: {:?}", buckets);
    //
    // Since the crate is not yet available, this code is only illustrative.
    println!("The Rust SDK for Google Cloud is now available for use.");
