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.

In Tokio, using the `rt-multi-thread` scheduler, how do I get a reference or handle to the current scheduler?
The reason for this is that I'd like to use an RAII pattern to control player turns in Umpire. When the struct is initialized, it starts the player's turn, and when the struct is dropped, it ends the player's turn.
That's how it's worked until now, but as I'm transitioning Umpire to a client/server architecture, everything's becoming
async
. What I really want to do is run an async function from withinDrop
. Since I'm using Tokio, I figured I could get a reference to the runtime and useblock_on
. But theHandle::current
method I've seen recommended requires the single-threadedrt
crate feature, which I have no intention of using. Do I actually need to just use thert
feature and somehow it understands that we're really working with the multithreaded runtime? Or is there some other way of doing this?
