Error tooltip wrapping at a weird spot

[CodingDoll]

The line break before the backtick causes incorrect Markdown rendering.

The reason is that rust-analyzer responds with a \n before the backtick.

Steps to reproduce:

1. Create a new project with cargo new.
2. Rename src/main.rs with src/lib.rs.
3. Override the contents of the file with this.

code snippet to reproduce:

mod front_of_house {
    pub mod hosting {
        pub fn add_to_waitlist() {}
    }
}

mod customer {
    pub fn eat_at_restaurant() {
        hosting::add_to_waitlist();
    }
}

rust-analyzer version: 0.3.2743

rustc version: rustc 1.91.1 (ed61e7d7e 2025-11-07)

editor or extension: VSCode

That diagnostic is coming from rustc, and it includes a newline because rustc includes the full text it suggests to insert, which includes a newline after the use.

I'm afraid we can't really do anything here.

I notice that. rustc outputs help information as shown below, could rust-analyzer wrap the code snippets with ```?

Is the rustc diagnostic even supposed to be markdown?
