Rust-Editor only syntax coloring

[Krzmbrzl]

When opening a Rust-file inside eclipse with the corrosion plugin installed, I do not get any features except syntax highlighting. Whenever I am in the code and do Ctrl+Space it will tell me that there are no completion proposals. If I do the same in empty space I get a few entries in it but nothing too helpful.

Also I do not get any error-markers no matter what I type in the source code (There are no problems in the problems view either).

I am not quite sure if it may be a problem that all Rust files are being opened in the Generic Text Editor but I couldn't find a Rust-editor so I guess this is the correct one?

I am using eclipse version 2018-09 and Corrosion v0.3.0

Can you please check the error log in <workspace>/.metadata/.log ?

[Krzmbrzl]

It says

!MESSAGE RLS settings for Corrosion path not set.

Before that it said that it couldn't find the setting at the path specified in the settings (It was set to /home/<username>/.cargo/rls.conf). I googled and found #186 in which you wrote

the .cargo/rls.conf file contains the startup settings for the rls and it is optional. If you don't have one, Corrosion will ignore it and guess some sensible (!) defaults.

So I thought that maybe removing that preference might help. But obviously it doesn't ^^

Okay I just tried it with Eclipse 2018-12 and now it seems to be working. However now it shows me errors where there are none.

The project compiles just fine but it says it can't find an import. (The import is from within the current project. All external imports (std-lib) are resolved properly. Is there a setting for the include-path?

Is there a setting for the include-path?

All rustc's path management is done via cargo and rustup within RLS.

Try restarting it. For some reason, I've found that you have to restart Eclipse after you use extern crate current-project in order for it to load.

That's interesting. Can you please create a dedicated issue about this ?

[mickaelistria]

Can you please try with the 2019-06 release candidate: https://www.eclipse.org/downloads/packages/release/2019-06/rc1

Cannot reproduce and no news for 3 months, closing.

Still have this issue with Eclipse IDE for Rust Developers (2020-09 (4.17.0))
Just downloaded and installed Rust & Eclipse from the official sites.
