Asynchronous Programming Development Tutorials, Guides & Insights

You can chain multiple generators to create data pipelines. For example:

def generate_numbers(start, end):
    for i in range(start, end):
        yield i

def filter_even(numbers):
    for num in numbers:
        if num % 2 == 0:
            yield num

def square(numbers):
    for num in numbers:
        yield num ** 2

# Chaining
numbers = generate_numbers(1, 10)
even_numbers = filter_even(numbers)
squared_numbers = square(even_numbers)

print(list(squared_numbers))  # Output: [4, 16, 36, 64]

• Conditional Breakpoints:

You can also set conditional breakpoints, which only pause execution when a specified condition is met.

function fetchData(callback) {
    setTimeout(() => {
        callback("Data fetched");
    }, 2000);
}

console.log("Start");
fetchData((message) => {
    console.log(message);
});
console.log("End");

Start
End
Data fetched

• await suspends the function’s execution until the Future is ready.
• It allows the program to remain responsive while waiting for long-running tasks to complete.

Rust’s powerful error handling mechanisms work seamlessly with async code. You can use Result, ?, and other constructs within async functions just like in synchronous code.
