intellij-lsp-server VS intellij-rust

I once had the idea of implementing an LSP server by embedding it as an IntelliJ plugin and backgrounding the IDE while doing the actual coding in Emacs.

It kind of worked, but once I stopped needing to use Java for my job it became too much of a hassle to flesh out.

The LSP means every single language server has to reinvent the wheel again and again.

It’d have been much more useful to build bindings for IDEA plugins so they could be integrated into arbitrary editors, especially as the IDEA plugins for most languages even after several years of LSP development are still superior.

All in all it’s like the whole JVM vs. WASM, Java vs Electron story again, with someone deciding to reinvent the wheel but worse.

There’s even bindings like https://github.com/Ruin0x11/intellij-lsp-server or https://plugins.jetbrains.com/plugin/10209-lsp-support to glue it all back together.

It’d have been much simpler to reuse an existing ecosystem from the start.

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
