question - how to get stdlib sources for intellij?

Hi, this is more of a question than a bug, I hope you don't mind me asking here.

I have installed rustc etc with this asdf plugin and that's all working great.

When I open the project I'm working on in IntelliJ (CLion) with the [IntelliJ Rust plugin](https://intellij-rust.github.io/) it can't find stdlib and asks for the location or `rustup`. Having looked around it seems this plugin only installs the tool binaries (which makes sense), so I don't currently have the sources it's looking for.


I haven't installed rustup as presumably that overlaps in purpose with asdf. I don't really want to mess up my asdf setup by using rustup so I'm not sure what to do.

I got this working as per https://stackoverflow.com/questions/41464063/how-to-provide-standard-library-sources-for-intellij-ideas-rust-project/63934669#63934669 by downloading and extracting the sources directly from the source code links at the bottom of https://forge.rust-lang.org/infra/other-installation-methods.html#source-code and telling IntelliJ where to find them:

I guess ideally it'd be cool if this asdf plugin could also pull in the sources needed for intellij to behave.

Start by reviewing the asdf-rust plugin's installation behavior and the Rust source-code installation links referenced in the issue. Determine how the plugin could provide sources that IntelliJ Rust can locate without rustup; done means a documented or automated setup supplies the required standard-library sources.
