RLS fails for format code

[ctron]

As reported in eclipse-corrosion/corrosion#252 the RLS fails to format the code with:

[t=1562070660321] LSP4E to org.eclipse.corrosion.rls:
{"jsonrpc":"2.0","id":"11","method":"textDocument/formatting","params":{"textDocument":{"uri":"file:///home/jreimann/Development/workspace-esp32-rust/rust-esp32-hono/src/main.rs"},"options":{"tabSize":4,"insertSpaces":false}}}
[t=1562070660322] org.eclipse.corrosion.rls to LSP4E:
{"jsonrpc":"2.0","error":{"code":-32603,"message":"Reformat failed to complete successfully"},"id":"11"}

Hey, thanks for the report! Looking at the original issue, you said you happened to reproduce it using https://github.com/itadinanta/gfx-gtk. Did cargo check compile the project successfully in that case?

[ctron]

cargo check fails as the target is unknown to the locally installed toolchain. However that shouldn't prevent it from formatting the code IMHO.

I think #1533 may help with this case too, can you retest with the latest code?

[norru]

Hi @alexheretic, #1533 fixed it for me, many thanks!

@ctron, worth another shot?

[ctron]

Sure, what do I need to update?

[norru]

A simple rustup update did it for me a few days ago. I am on nightly though.

[alexheretic]

I believe #1533 won't be on stable until the next release, I've been using beta channel rls recently because of that.

[ctron]

Ok, I did a rustup update as few days back. But I am on stable, and still have the same issue.

[norru]

@ctron as @alexheretic said, it probably hasn't made it through to stable yet.

[alexheretic]

On stable now :)
