What's your coc-rust-analyzer version? You can get it from :CocList extensions
coc-rust-analyzer 0.75.1

Given this simple rust snippet code:

struct Hi {
    field: String,
}
    
impl std::fmt::Debug for Hi {
}

If I were to activate code action "Implement missing members" for this impl Debug, I will get a number of backslashes specifically preceding the closing brace:

impl std::fmt::Debug for Hi {
    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        f.debug_struct(name: "Hi").field(name: "field", value: &self.field).finish()
    \}
}

rust-analyzer https://github.com/rust-lang/rust-analyzer/releases/tag/2024-02-19 brings this bug, 2024-02-12 is working as expected.

Tracking issue for bug: rust-lang/rust-analyzer#16607 seems to be fixed since very recently

[theKidOfArcrania]

I don't think, however, it actually properly fixes the bug tho

[fannheyward]

Made a quickfix in v0.75.2, to trim \\ for this case.

I'm still running into this issue if I generate multiple trait methods. I think the issue is because replace was used instead of replaceAll

[fannheyward]

@RustyYato try v0.75.3

[RustyYato]

That worked, thanks for the fast response!
