Thank you're a lifesaver, IDK about the error message on the top didn't configure much except nord-night theme must be a bad design choice on helix's part

    fwiw if you do a cargo build you should be able to see the error messages in the correct context. If I replicate line 25 in a little test project and run cargo build I get

    error: expected one of `.`, `;`, `?`, `else`, or an operator, found `{`
 --> src/main.rs:4:43
  |
4 |     let guess: u32 = guess.trim().parse() {
  |                                           ^ expected one of `.`, `;`, `?`, `else`, or an operator

error: could not compile `unacceptable-rs` (bin "unacceptable-rs") due to 1 previous error

    If I try this with a blank helix config I don't get any of the text output from rust-analyzer at all, just the three dots indicating there's a problem there, so it's unlikely it's a bad design choice on helix's part.

    Inline diagnostics was implemented earlier this year, and is still not enabled by default (likely to prevent breaking existing configs). The changelog is from January of this year:

    https://helix-editor.com/news/release-25-01-highlights/

    You can set it up here, and is straightforward:
