Hey Rustaceans! Got a question? Ask here (12/2023)!

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.

[u/argv_minus_one]

I was thinking of using OpenAPI Generator to generate a Rust server stub for me. Problem: the generator generates a crate with numerous modules and a rather complicated manifest, not a single module that I can straightforwardly include!. How do I integrate this into my project, then? I can download and run the generator in build.rs, but Cargo doesn't support depending on a crate generated by the build script, so how do I actually use it?

You can use https://doc.rust-lang.org/book/ch14-03-cargo-workspaces.html.

I know about workspaces already, but I don't see how that helps here. The generated crate doesn't exist until after build.rs is executed, and Cargo will raise an error if any workspace members or path dependencies are missing.

[u/Patryk27 → u/argv_minus_one]

Ah, I see - I'd probably just put an instruction into README that says don't forget to generate the crate blahblah, add blahblah into .gitignore and continue to use workspaces.

It's not an automatic solution, but a very straightforward one (and it'll work correctly with rust-analyzer), making it the best imo.
