#An insane amount of error files on RustRover, plus build issues

I get an insane amount of compilation error files on RustRover, and I have no idea why. The project usually builds fine once or twice after a cargo build but then throws one of the errors in the files (which does not come with a highlighted line of something, it just says "failed to xyz" and I clean and rebuild the entire thing every time).
I'm attaching a video of the insane amount of files and will also send some of them here.

Would greatly appreciate some help with that, it's been going on for quite a while and it's starting to break me too (not just the compiler).

What does rustup show say

#

It very much looks like an incremental bug of some type

(I'm going to sleep soon but feel free to ping me and I'll come check in the morning)

and then rebuilding?

Ohh @stark temple I 've noticed that RustRover sometimes get's out of sync with local rust environment, I learned uninstalling it, wiping out all cache and data leftovers https://www.jetbrains.com/help/rider/Uninstall.html#standalone then reinstall it clears up a-lot of these sort of incremental bugs.

Also there's an option in RustRover File > Repair IDE which goes thru progressive troubleshooting steps, or a intermediate nuke which is File > Invalidate Caches (I usually check first two) and that sometimes works as well.

Finally I've been using VSCode as a lightweight fallback.

As a not jetbrains user this is probably more helpful than I can be

Ohh I pinged the wrong person

#

#

I meant to ping the OP?

#

@tender cobalt sorry I meant to ping you.

so rustrover is messing up the cache

#

also

tender cobalt
#

I'll try clearing the cache and if that doesn't work I'll reinstall

What IDE do you guys use?

#

let me tell you what to expect

#

up to 2x compile speedup

#

less ram usage

#

no more ms spyware

tender cobalt
#

I don't mind the spyware

#

Faster rust is like
the one reason for me to switch

#

I'll think about it (but probably won't do it due to time consumption)

hushed frigate
#

those are pretty stable and easy to install

#

You guys are hardcore haha

tender cobalt
hushed frigate
#

thats why i recommend it

tender cobalt
#

I will consider it, if that means a faster rust

hushed frigate
#

i havent tested but im also pretty sure it means faster c/cpp

#

and its less painful to do stuff

#

because if you need a library

#

you can just get it with 1 command and continue your day

#

do you know how it is on windows?

#

you have to find it on the internet

#

download it

#

extract it

#

think of where to put it

#

change your path

#

reboot

#

and then finally

#

you have the lib

#

(if the thing you need can find it )

Actually I just cargo add

Mainly Neovim. I used RustRover a bit and its probably what I would recommend for a new Rust developer.

rustrover for work, I typically have to invalidate caches 1-2 times per week
