Invalid offset -32603 when editing an empty .rs file

[goldeneas]

rust-analyzer version: 2024-05-09

rustc version: (eg. output of rustc -V): 1.78.0

editor or extension: neovim with Mason+Lspconfig+RustAnalyzer

relevant settings: none

repository link (if public, optional): none

code snippet to reproduce:

Rust analyzer is printing this error if I start editing an empty .rs file before it has completed its startup. There are no settings involved, just an empty cargo project with a main.rs. Once that error pops up, it will keep appearing on every keystroke until I close the buffer, reopen it, wait for it to fully initialize and then start writing. This does not happen if the file is not empty.

I had the same issue today using Mason+Lspconfig+RustAnalyzer as installed by Mason. I tried rust-analyzer -V in the terminal and the output was error: Unknown binary 'rust-analyzer' in official toolchain 'stable-x86_64-apple-darwin'.

I'm not sure what the root cause of this error is, but following this Stack Overflow link, I tried

rustup component add rust-analyzer

I no longer had the terminal Unknown binary error or the buffer Invalid offset error in neovim. Could be some Mason issue.

I ran that command and it also showed that error about the toolchain not being installed. However even after installing it the situation is the same.

[tejasprabhune]

You're correct, I mistakenly thought the problem was resolved. I am having this problem as well.

This makes me believe that it might be an mason/lspconfig bug? (we should probably tell the invalid offset in the error message here)

Happens to me too in Neovim with Mason + Lspconfig on macOS

Can you check whether this occurs with a previous rust-analyzer version? It's not clear if this is a rust-analyzer bug or maybe a change in mason/lspconfig that surfaced this.

It happens for quite a while, in multiple Rust Analyzer versions.

@yuvaldolev how do you install it, using rustup, or from source / GitHub releases?

I installed rust-analyzer using Mason (Rust itself is installed using Rustup but not rust-analyzer).

BTW this error seems to happen in other times than just editing an empty file. It happens to me once in a while when coding in Neovim, which is a real bummer as I have to reopen Neovim and lose the state of my project (doing LspRestart doesn't solve this... I must reopen Neovim to fix it).

[yuvaldolev]

@lnicola @Veykril Is there any update on this?
It's quite hard to use rust-analyzer with Neovim as it currently is.

[goldeneas]

I am still experiencing this issue. I've noticed that it also rarely happens when the buffer is not empty if I start editing it while rust analyzer is still indexing files.
I haven't tried using older versions, and I've always installed/updated mine using Mason.
If no one else has tried using older version I could do that, or if anything else should be tried.

[Veykril]

In what r equest handler is this happening? The logs should tell that. I am unsure what the cause here is, given it only seems to occur for this specific editor setup

I am not using mason for rust analyzer. Here's what the lsp log shows when I encounter an error:

The error occurs in the textDocument/inlayHint method and I have also encountered it with textDocument/documentHighlight.
