Rust Async Skill

Tokio Basics

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

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

Spawning Tasks

rust
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
