Rust Async Skill

Tokio Basics

#[tokio::main]
async fn main() {
    let result = fetch_data().await;
}

async fn fetch_data() -> Result<String, Error> {
    // async operation
}

Spawning Tasks

let handle = tokio::spawn(async move {
    expensive_operation().await
});

let result = handle.await?;

Send + Sync Bounds

• Send: Can transfer across thread boundaries
• Sync: Can be shared across threads (&T is Send)
• Use Arc instead of Rc for thread-safe reference counting

Review Severity

• CRITICAL: Blocking calls in async functions
• MAJOR: Using Rc in async code (not Send)
• MINOR: Not using async context managers
