No code autocomplete about coc-rust-analyzer

[oblitum]

@ovidius72 try to provide more detail taking coc.nvim issue template as a model: https://raw.githubusercontent.com/neoclide/coc.nvim/master/.github/ISSUE_TEMPLATE/bug_report.md. It's hard to have an idea without info.

Do you test with a single rust file or a project with Cargo.toml ?

[ovidius72]

It's a project with cargo.toml file.
I did more tests and found this.
I've created a file user.rs under the src directory. Working on that file auto completion does not work until you go in the main.rs file and import it with mod user;. Doing that I can see that everything work just fine. So it seems that it only works if you use that module in the main.rs file, otherwise not.
Can you please test if this is the same for you ? thanks
I'm learning rust so it could be that I'm doing it wrong but I suppose that all .rs files should be detected by rust-analyzer.

You can test your code with VSCode+rust-analyzer to make sure it works or not.

thanks @fannheyward It doesn't work in VSCode+ra . The same thing happens. I don't know if it is the wanted behavior but this has nothing to do with coc-rust-analyzer. If it is an issue, it is related to rust-analyzer itself.
Thanks.

Had the same issue after upgrading the rust-analyzer binary to 2020-04-27. So I manually download and replace the installed binary to https://github.com/rust-analyzer/rust-analyzer/releases/tag/2020-04-20 and now works again.

@fannheyward is there an option to let this plugin choose which version of rust-analyzer to install? That would be handy in cases like downgrading to some version specially since rust-analyzer is not yet stable.

The latest release is 2020-05-04, you can test the new release.

the problem is here I guess: rust-lang/rust-analyzer#4177
