Another workaround is to use the pre-release version 0.4.1851
For me pre-release version 0.4.1851 and version 0.3.1850 show the same behavior. v0.3.1839 is working correctly.
This seems to be non-deterministic ...
Also affected. Fetching eventually finishes, but it easily takes half an hour. Afterwards it is responsive until I run a build on the command line (which, after rust-analyzer ran requires rebuilding half the application starting from proc_macro2, even if there were no changes). So it seems like rust-analzer invalidates regular builds and vice versa.
Reverting back to 0.3.1839 fixed the issue for me as well.
Most likely caused by https://github.com/rust-lang/rust-analyzer/pull/16537 / https://github.com/rust-lang/rust-analyzer/pull/16563, I only ran into it once earlier but I can't seem to reproduce it now.
Actually it could beis https://github.com/rust-lang/rust-analyzer/pull/16247
For the time being you can disable rust-analyzer.cargo.buildScripts.rebuildOnSave
, that should avoid the issue until a fix is landed I think.
https://github.com/rust-lang/rust-analyzer/pull/16616 should fix this I believe, I pushed out a new nightly release if some of you could check with the rust-analyzer.cargo.buildScripts.rebuildOnSave
enabled again on that release that would be great
v0.4.1852 is still hanging for me :c
Same here, downgraded to 0.3.1839
Mine was also fetching for about 10 minutes, deleting some of the compiled project and seemed to have a hard time determining types, reverting to 0.3.1839 also fixed mine.
same here. both in stable v0.3.1850 and in v0.4.1853 (pre-release).
Same for me in Linux. Both v0.3.1850 in vscode and v20240219 for helix I encountered similar problem. Once I launched the editor, there would be multiple rustc running in bachground for a long time.'
Another issure: when the analyzer found #![cfg_attr(rustc_attrs, feature(rustc_attrs))]
error in a dependency crate, it stopped error checking in the workspace, but I can still compile the project without this error.
The problem for me got fixed after changing rustc
to nightly version. rustup default nightly
. Make sure to build your project with cargo build
before you open your editor, which will launch rust-analyzer and index it. Otherwise, your rust-analyzer will have to compile by itself, which will result in a very long wait time if you are building bevy.
In general it seems that the issue can be sidestepped by first building the project via a manual cargo invocation before loading up rust-analyzer. I'll try looking into this more by the end of the week.

@Veykril That is not exactly what was happening to me, that's how I used to do it before the problem arose, I would build because otherwise the indexing will take much longer.
As of right now After running cargo build
I open the files for editing, and rust-analyzer get stuck at fetching. The fetching phase takes as long as the building phase, as if rust-analyzer have to rebuild everything itself before indexing. After that the build I did previously with cargo build
gets invalidated, so no incremental builds and if I build it again then it will have to build it all over again from the start and takes as long as it did the first time.
And If I open the project again now, rust-analyzer does what it did again and rebuild + invalidate my manual cargo build. Even if I close my editor and re-open again without running cargo build
, rust-analyzer will do it again from the start. And this will keep happening unless I have the analyzer already indexed and build through built in terminal.
There were various steps I took to try and address this problem, including setting analyzerTargetDir to true. In the end, as of right now, I'm not exactly sure what fixed the issue for me. Nightly seems not to be the fix, when I switched back to stable I found that the problem has come back, but switching back to nightly didn't fix it this time.
Apparently I could get rid of the problem by disabling opt builds and the dynamic_linking but only on nightly rustc, stable still has the issue even with those disabled.
Build invalidation is a different problem than the one described here. I am having problems reproducing this issue again right now (been trying to bisect it with no luck)
I'm running into this issue. My fix is to uninstall rust-analyzer in VS Code, and reinstall. It'll work fine into the next time I open the editor.
Hi. For me it still stuck after uninstalling and reinstalling version v0.3.1850
. Stucked message is
Building: building proc-macros: <APP_NAME>
(similar to https://github.com/rust-lang/rust-analyzer/issues/16605)
I finally solved my problem by updating my toolchain (rustup update
) from version 1.75.0
to 1.76.0
Updating the toolchain helps? :raised_eyebrow: now that would be very confusing to me.
Just ran into it again earlier, from the looks of it it seems that the server deadlocks somewhere
Alright it can easily be reproduced by just editing a proc-macro in the loaded workspace, captured a backtrace of the running lsp-server

Hmm no that doesn't seem right, 11 is in a spinlock
0.4.1843 seems to be good, 0.4.1849 shows the issue, commit range https://github.com/rust-lang/rust-analyzer/compare/b9b0d29b8e69b02457cfabe20c4c69cdb45f3cc5...68c506fd6299c60c96a6202ca08f9d868a0838a3
Ah nevermind it is the two threads I think I found the problem
Full rebuild (Fetching...) on each save ("rust-analyzer.checkOnSave": true). Extension version: v0.4.1856 (pre-release) Using Bevy 0.13 crate in project. Rust-analyser extension 0.3.1839 works fine. Am I do something wrong, or problem is still not solved?
I'm also still having the issue where it hangs at building proc-macros: <PROJECT_NAME>
. I'm using nvim and rust-analyzer 1.78.0-nightly (3cbb932 2024-03-13)
currently. Is the fix not in nightly yet?
I am getting completions however, but no diagnostics for my code.
I don't exactly know the release cycle of nightly and stable yet, so there just might be something that I'm missing here.

@LucaSchwan I'm not sure how you installed rust-analyzer, but the deadlock corresponding to this issue has been resolved and released. If you installed rust-analyzer through rustup, it seems like the last sync was four days ago: https://github.com/rust-lang/rust/pull/122272.
@davidbarsky I am on NixOS and I'm using fenix with a flake to install the nightly toolchain.
I'm also running into the building proc-macros: <PROJECT_NAME>
issue. Tried toolchain versions 1.77.2
, 1.78.0
, 1.79.0-beta
and 1.80.0-nightly
via rustup but all of them present the problem. Downgrading to 1.76.0 (07dca48 2024-02-04)
solved it for me, and I can confirm that 1.75.0
also works fine.
rust-analyzer version: 0.3.1850 (latest at time of writing)
rustc version: rustc 1.78.0-nightly (3246e7951 2024-02-19)

(I am using VSCode)Like in the title, rust-analyser hangs at "Fetching" when starting the project, if I click on show logs it doesn't show anything, but it keeps using the CPU with multiple rustc processes at 100%. I tried cleaning up the cache, reinstalling rust, messing with num thread and cache priming settings, but nothing worked.
The only thing that worked to make it usable was to revert to v0.3.1839, and now everything works fine. I will stay on that for now until it gets fixed :)
