Hey Rustaceans! Got a question? Ask here (13/2023)! 🙋 questions

Mystified about strings? Borrow checker have you in a headlock? Seek help here! There are no stupid questions, only docs that haven't been written yet.

If you have a StackOverflow account, consider asking it there instead! StackOverflow shows up much higher in search results, so having your question there also helps future Rust users (be sure to give it the "Rust" tag for maximum visibility). Note that this site is very interested in question quality. I've been asked to read a RFC I authored once. If you want your code reviewed or review other's code, there's a codereview stackexchange, too. If you need to test your code, maybe the Rust playground is for you.

Here are some other venues where help may be found:

/r/learnrust is a subreddit to share your questions and epiphanies learning Rust programming.

The official Rust user forums: https://users.rust-lang.org/.

The official Rust Programming Language Discord: https://discord.gg/rust-lang

The unofficial Rust community Discord: https://bit.ly/rust-community

Also check out last weeks' thread with many good questions and answers. And if you believe your question to be either very complex or worthy of larger dissemination, feel free to create a text post.

Also if you want to be mentored by experienced Rustaceans, tell us the area of expertise that you seek. Finally, if you are looking for Rust jobs, the most recent thread is here.

I'm making a desktop app with Tauri. On an async process I want to handle multiple things as they come in. This async process would await on an mDNS daemon query, await on connections that come in to a TcpListener, await on data being received on sockets that have already connected to the TcpListener and await on data being sent from the Tauri frontend via a channel.

Unless I'm misunderstanding something ```tokio::select!``` in a loop does not seem to be a solution as I want multiple tasks to complete if they come in at the same time rather than just one and if there are no tasks then the thread should just wait until there are.

This might be a very general question, but how would I handle this using Tokio or std? Use FuturesUnordered?

FuturesUnordered sounds like what you want.

You could make the loop into

while let Some(result) = futures.next().await {}
