Pasting special yanked scharacter in &str gives Syntax error that only goes away after :lsp-restart or undo

[th7mo]

Summary

I am editing a rust file with the following code:

let x = "═";

!Note that this is not a normal character, but a special box drawing unicode character!

When I navigate to the ═ character and yank it, it will give a syntax error warning when trying to paste it into the &str:

The error goes away when I hit undo.

Reproduction Steps

I tried this:

1. hx .
2. navigate to main.rs
3. write let x = "═";
4. yank the character in between the equal signs
5. paste the character so it gets inserted in between the equal signs

I expected this to happen:
No error because this is valid rust code (checked with rust playground and it compiles without errors)
https://play.rust-lang.org/?version=stable&mode=debug&edition=2021&gist=b3867553cbdd613001d336a0cd19e314

Instead, this happened:
I got an syntax error that only goes away when I restart the lsp server or hit undo

Rust analyzer only updates most diagnostics on save so you need to save the file for that diagnostic to update. From your lognitnlooks like you never saved.

Generally language specific bugs like these are.never related yo.helix itself and instead the language server for the various languages (rust-analyzer in this vase). Helix doenst implement any language specific logic.

#6447 improves this somewhat with better tracking for these kinds of "updated on save diagnostics" but the same issue exists in vscode so it's really just a trick i added to work around the LS (rust-analyzer) shortcomings.

hi @pascalkuthe , thanks commenting on this!
In my example I indeed did not save, however:
It is still an after i :write the file:

I just got started out with using LSP's, so I don't know if this is an issue with the rust-analyzer or that helix can do something to resolve this incorrect syntax error.
