(When I first saw the link I was wondering if JetBrains had decided to release a Rust-centric IDE, and was briefly excited (tho I have a CLion license) but seems that's not the case.)

FWIW latest changelog on the plugin @ https://intellij-rust.github.io/2023/07/10/changelog-198.htm...

- More than half of compile time errors are not shown in the IDEs. - Breaks when using some macros. For example wheb using gtk-rs each file defining a custom widget constantly show 2 errors that aren't there. Autocompletion fails for a lot of macros, even simple ones with macro_rules!. - The debugger works but there are no type renderers. I wish it showed the result of Display or Debug. Often you have to go through 5-6 layers of objects to find the actual data with std types. Single stepping can be very slow at times. Runtime expression evaluation almost always fails except for very simple expression like accessing a field (forget about anything that creates structs). - Finding files with double Shift is usually very fast but for some reason it can take 6-7 seconds for Rust files to show up.

Kidding aside, this is nice! Always happy to see more support for Rust, and I'm usually pretty impressed by what JetBrains brings to the table in their IDEs, so this is promising! Hopefully this will be one of those cases where the less you need an IDE, the more comfortable the features are for the ones that are built.

I've generally seen the release of a branded IDE for a language from Jetbrains to be when they have great support for it, hopefully it'll come for Rust but it's taking a long time, which unfortunately for a Jetbrains user to death at this point, means not using Rust itself.

I usually turn the setting on, but there are a few projects that do make the UI sluggish where u have to turn them off. I'm not entirely sure what the problem is, some code with many dependencies works absolutely fine while some code with only basic crates turns into a lagfest. My suspicion is that there's a crate somewhere deep down the dependency tree that makes use of some very intensive macros that trip up the tooling.

I've also noticed that the most recent release of Rust made working with the tooling feel a lot snappier. Not sure what changed, but it's nice to see.

One laat thing I always recommend anyone running into weird IntelliJ/Clion/IDE slowdowns: check the difference between antivirus off/on to see if that influences things. Windows Defender just can't seem to deal with a program opening many small files. What this means for you depends (you probably shouldn't disable AV on a company laptop) but it may solve the mystery why your experience doesn't match other people's.

Especially if you happen to be doing anything like using WSL or a mounted network share. For example, I had to do a lot of workarounds to resolve indexing and line ending issues while working on a Windows machine and running my code on a remote container server running nix.

This hasn't been fixed, but it's my biggest pain point.

> felt very sluggish to me

We're working in a Rust workspace monorepo with about 30 crates and it feels fast.

I bought 16GB a decade ago, for example, so I wouldn’t have swapping issues with my tools. That machine is still usable today.

"Its sooo slow"

I am not sure why people use these tools, I've tried and they seem at best on-par, at worse, sooo much worse. I get real Microsoft vibes, a sales team comes in, takes the purchasing team to a concert/sports and dinner to 'discuss business'. And its announced that everything needs to be done on M$ sharepoint/Intellij.
