cannot jump to code generated by tonic grpc

[0x8f701]

Hi, I found it's impossible to jump to code generated by tonic, is it unimplemented ?

[bjorn3]

Did you enable rust-analyzer.cargo.loadOutDirsFromCheck?

[0x8f701]

hi @bjorn3 I just enabled it but it still doesn't work, I'm using coc-rust-analyzer + coc.nvim + rust-analyzer

Fwiw enabling rust-analyzer.cargo.loadOutDirsFromCheck fixed this issue for me in VS Code

[lnicola]

Are you using nightly? If so, can you try with a new rust-analyzer?

Also, how did you enable the setting?

@lnicola -

Are you using nightly?

Yes, I'm currently using rustc 1.49.0-nightly (a1dfd2490 2020-10-05)

If so, can you try with a new rust-analyzer?

I'm using the latest master, built fresh a couple of hours ago with cargo xtask install

Also, how did you enable the setting?

I just added this line to my VS Code settings.json:

"rust-analyzer.cargo.loadOutDirsFromCheck": true,

Sorry, I was asking @GopherJ since for you it already works.

[0x8f701]

Hi all, thanks for your replies, I confirm that I'm using nightly but I'm not using VSCode, I use vim + coc.nvim + coc-rust-analyzer

@inicola is it a problem on coc-rust-analyzer side?

You can see all my config at: https://github.com/GopherJ/cfg/tree/master/coc

[lnicola]

It's hard to tell, but if you're using proc macros with a nightly rustc newer than 1.45, you'll need a rust-analyzer that includes #5651, otherwise it will crash.

It's unlikely, but it could also be a coc-rust-analyzer issue.

needs a minimal reproducible examble to become actionable. THe action would be to check with vs code if i works.

[0x8f701]

Hi @matklad thanks for your reply, I should have done it :) sorry.

I confirm it's more a pb on coc.nvim + coc-rust-analyzer because it works perfectly in Vscode but not with coc.nvim + coc-rust-analyzer

[lnicola]

Closing for now, we can reopen or file a new bug if we're doing anything wrong.

[lnicola]

CC #3767 -- I think?

[lgln]

I have the same issuse, is there some progress?

[flodiebold]

@lgln can you give a minimal reproduction of the issue?

[lgln]

use hello_world::greeter_client::GreeterClient;
use hello_world::HelloRequest;

pub mod hello_world {
tonic::include_proto!("helloworld");
}

i want to find definition of "GreeterClient" in line 1, the cursor just jump to "tonic::include_proto!(" in line 5

my rust-analyzer is v0.2.583, my config in settings.json:

"rust-analyzer.cargo.runBuildScripts": true, 
"rust-analyzer.lruCapacity": 1024, 
"rust-analyzer.procMacro.enable": true,

It is easy to repro with https://github.com/shikhar/bazel-tonic/tree/4a27fbf7fe15a26804a3eb5eb3f7b62dafa9fba4

Generated code is included in lib.rs, and symbols from generated code are used in client.rs and server.rs. Trying to jump to definition from those symbols takes you to the include in lib.rs, instead of the generated source file.

This seems like a duplicate of #3767.
