def subgenerator():
    yield "A"
    yield "B"
    yield "C"

def delegating_generator():
    yield "Start"
    yield from subgenerator()
    yield "End"

for item in delegating_generator():
    print(item)
# Output: Start, A, B, C, End

This is useful for composing complex generators.

• Recording a Performance Profile: Click the record button to capture a performance profile while interacting with your application. Once the recording is complete, you can analyze the profile to see where the most time is spent.
• Analyzing the Flame Chart: The flame chart shows a visual representation of the call stack over time. The wider the bar, the more time was spent in that function. This helps you identify functions that may need optimization.

Writing maintainable code reduces the likelihood of introducing errors and makes it easier to debug and extend your application.

Using Async/Await:

To use await, the function must be declared with the async keyword. The await keyword is used to pause the execution of the function until the promise is resolved or rejected.

The await keyword is used to pause the execution of an async function until the Future it is working on completes. This allows other tasks to run concurrently while waiting for the result.

async fn main() {
    let data = fetch_data("https://example.com").await.unwrap();
    println!("Fetched data: {}", data);
}
