Format `let_else`/let else

[cynecx]

It seems like rustfmt doesn't support formatting let_else/"let else" constructs right now.

fn main() {
    let Some(okay) = Some(1) else {
                            let t =             1;
                    return;
    };
}

I also couldn't find an existing issue around let_else (searched for "let else" and "let_else"), so let me know if this is an existing issue that I wasn't able to find.

Thanks for reaching out. rustfmt doesn't handle let-else formatting because the rules for how it should be formatted are still being discussed in rust-lang/style-team#165

You might also want to follow #4914 to keep track of the implementation on the rustfmt side once the rules have been codified in the fmt-rfc linked above.

@ytmimi Oh dang! I was searching for "let else" and "let_else" and not "let-else". Do you mind adding "let_else" (and "let else") to the title of that issue so other lost minds have it easier finding that issue? :)

No worries, it can definitely be challenging to sift through the backlog. I struggle to track down issues I know are there all the time 😅

I'm surprised "let else" didn't work. This is what I got when I search for "let else" (2nd result)
