Panic: 'missing key in compiler_jobs'

[Marwes]

Getting a crash when using rls with https://github.com/autozimu/LanguageClient-neovim/. Didn't have backtrace enabled at the time of the crash but I have enabled it now and will update this issue if it re-appears

I believe this is a racer issue, probably dependent on specifically how the file is being edited

[kngwyu]

It's definitely a racer bug and I'm really interested in this problem.

@Marwes
Can you please note the file name you were editing, if you remember it?

[Marwes]

@kngwyu I believe it was src/config/mod.rs

[kngwyu]

@Marwes
Thanks, but I forgot asking the crate name you were working at.
Can you please note it?

[Marwes]

The name of the crate is api but it is proprietary so I am afraid I can't divulge anything more than that.

[kngwyu]

Oh, so I'm sorry it's difficult to debug...
Anyway, now I know there's some bug around racer's get_struct_field_type, so thank you very much for reporting.

I think that this consistently happens for me - If you need my sources tell me and I'll upload them.
EDIT: another panic, with the message "out of order or duplicate change"

I'll try to make this happen with RUST_BACKTRACE=1, but here is the output for now:

I get the same(?) error. Strangely there is no backtrace even with RUST_BACKTRACE=1:

Edit: rls-preview 0.126.0-nightly (f5a0c91 2018-03-26), VSCode RLS plugin 0.4.1

[nrc]

This should be fixed with the latest nightly version of RLS.

[Diggsey]

@nrc the latest nightly does seem much improved: I was getting this issue constantly, and since upgrading, it hasn't happened once.
