intellij-rust VS rust-analyzer

We’ll also consider the cases when IntelliJ IDEA licenses were primarily bought for Rust development with the IntelliJ Rust plugin and which options we can suggest to our users in these cases. Please stay tuned!

Last time I tried this, the plugin was incapable of actually showing compile errors in the project view and they said their false positive error rate was too high to enable it (https://github.com/intellij-rust/intellij-rust/pull/8373). That was a dealbreaker for me compared to VSCode.

Intellgi Rust is a good option.

Thank you all for the assist. Yep, not just a newbie issue which is surprising. :^) https://github.com/intellij-rust/intellij-rust/issues/10483

Warning about Unused_labels and implementation of MIR Now things are getting interesting

Agreed. Specifically, I've found the intellij rust plugin on top of Clion to be great.

figure out testing, you probably want to structure your app in a way that allows you to run it in testing (Zero to Production has a great approach to that). There are helpers for testing like sqlx::test but CLion Rust plugin doesn't support them yet, it breaks code analysis (afaik the fix is not released yet).

Any closer to getting error highlighting on files working properly (https://github.com/intellij-rust/intellij-rust/pull/8373)? That's a major benefit of rust-analyzer to me.

Could you please clarify whether the problem affects exactly local variables' values or function parameters' values? It is a known bug that the CLion's debugger cannot show function parameters' values on Windows: https://github.com/intellij-rust/intellij-rust/issues/6676. This is a major issue and we are working on it. But if you are facing such problems in any other scenarios, please let us know and share a problematic code snippet if possible

I was looking forward to parallel front-end[4], but I have not seen any improvement for these small changes.

For example, intelephense can show diagnostics in real time, there is no need to save the file to get new diagnostics. But rust-analyzer, the language server for rust, can only update diagnostics after saving the file.

6. Rust Analyzer

The rust-analyzer readme suggests you go here for support request. But even there, you'll need to provide more details to get useful help.

For example: https://github.com/rust-lang/rust-analyzer/blob/master/docs/...

> If you create an LSP, it will work best in VS Code.

Any editor can work just as well as (or even better than) VS Code.

So, apparently the reason why rust-analyzer, the LSP server for Rust does not have persistent caching is because it would make "optimizing initial passes less important".

All I want to know is: Will it have a build configuration pulldown?

I am not a Rust dev. It surely looks great.

However, from what I understand it seems to supply just a parser separate from the Rust compiler (https://github.com/rust-lang/rust-analyzer/tree/master/crate...) trying to keep up with Rust‘s development. So, in principle, it could have been just another treesitter parser plugin, too.

So, again, the LSP framework does not directly provide any magical benefit over a static parsing framework. All the semantic analysis capabilities stem from a good parser.
