Nice writeup.

I don't see why you need async in your program - all you do is hit an api once, wait for the result and print it on screen. This program should work exactly the same without async/await.

A better example would be to pass multiple company names and fetch the data concurrently.

Also I don't think the ? operator is the same as unwrap. unwrap will panic the current thread if the result an Err, while ? will propagate it to the call site.

It's true that async is not needed but I wanted to show how to use async/await in Rust.

A better example would be to pass multiple company names and fetch the data concurrently.

Great idea! I will be sure to implement that type of tutorial soon. Also, the ? operator is not the same as unwrap, you're right. Since this post is more for beginners and it wasn't focused on the ? operator, I just wanted them to be familiar with the syntax and not have to worry about what it does.

Thanks for your input.
