Implement missing members introduces a \ before the curly braces of functions of a trait

[IceTDrinker]

rust-analyzer version: rust-analyzer version: 0.3.1850-standalone in VSCode

rustc version: rustc 1.78.0-nightly (2bf78d12d 2024-02-18)

relevant settings: nothing notable

/// A trait for types representing distributions.
pub trait Distribution: seal::Sealed + Copy {
    fn required_bytes_count_for_safe_generation<Scalar>(&self) -> usize;
}


impl Distribution for Uniform {
    // Cursor is HERE
}

Quick fix tooltip (ctrl + ; in my case) -> implement missing members

gets me

    fn required_bytes_count_for_safe_generation<Scalar>(&self) -> usize \{
        todo!()
    \}

which the compiler (and rust analyzer) obviously don't like

expected:

    fn required_bytes_count_for_safe_generation<Scalar>(&self) -> usize {
        todo!()
    }

Cheers

Previous version does not have the issue, I've reverted for now because it's not usable enough as is

Same happens with "Extract into function". Every generated curly brace gets preceded with a backslash.

Maybe related after a quick peek: 1d8ed34

Same is happening here, everything gets a \

Yeah just bumped into this but not in a impl in "Extract into function".

The latest vscode nightly extension (0.4.1852-standalone) includes #16475 which fixes } having a \ added before it. Unfortunately it still adds \ before any {, but fixing the latter is a simple change.

Just encountered this as well in VSCode. Confirming that switching to the current pre-release of the rust-analyzer extension and reloading fixes it.
