In this tutorial, I will be teaching you how to fetch a Web API asynchronously in Rust. This tutorial is for developers who know the basics of Rust...
For further actions, you may consider blocking this person and/or reporting abuse
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 asunwrap.unwrapwill panic the current thread if the result anErr, 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.
Great idea! I will be sure to implement that type of tutorial soon. Also, the
?operator is not the same asunwrap, 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.
Hey, what do you think of using unwrap_or for the optional parameter like in this Playground example here ?
Wow, that looks great. Thanks for the suggestion!
reqwest::get()makes a new http client on each call. use one client andget()from that if you are making many requests.
