ISSUE

When opening new, additional rust files in windows and tabs in neovim after the very first Rust file, the Rust analyzer does not activate for the subsequent files. The only workaround I have found so far is to execute :CocCommand rust-analyzer.reload to get the later files to have Rust code analysis.

For example: If I open an .rs file in neovim, it will have Rust analysis. If I open one or more .rs files in new windows or tabs within the same neovim instance, they will not have Rust code analysis unless I run :CocCommand rust-analyzer.reload

I do not see any possible configuration settings in the README.md that can address this issue and would like to know if there are any other methods besides having to run :CocCommand rust-analyzer.reload for each new tab or window that I open.

A new configuration setting that addresses this would be greatly appreciated.

My tests:

Cargo.lock
Cargo.toml
src/
src/main.rs

1. nvim src/main.ts, rust-analyzer launches and works as expected
2. tabnew to a new tab
3. some rust code, for example error code println!("{}", xyz);, :w src/lib.rs to new file
4. rust-analyzer reports diagnostic on xyz cannot find in lib.rs, without reloading

I've watchman installed, you can try https://github.com/neoclide/coc.nvim/wiki/Install-coc.nvim#install-watchman-for-file-watching

I have followed the installation instructions for watchman and have added it to my PATH. It does not appear to work and the documentation for Windows based systems is rather lacking.

Is this issue upstream in regards to the rust-analyzer or is it with the implementation of it in this plugin? It appears that I am the first one with the desire for rust-analyzer to work with multiple tabs and windows as I have not found any similar issues online elsewhere.

I would also like to add that :CocRestart also appears to have the same results as well, although I currently only have coc-rust-analyzer installed.

Still can't reproduce this on macOS, have no idea about this. It's properly issue of rust-analyzer. Can you reproduce this with VSCode + rust-analyzer?

I have been able to replicate the issue using a default VSCode installation and rust-analyzer installation acquired from here: https://marketplace.visualstudio.com/items?itemName=rust-lang.rust-analyzer. Any rust files opened after the very first one will no longer have error detection or code suggestion / completion.
