I downloaded an Eclipse's extinction for Rust, but then, after creating a new Rust project, i got this problem

I tried to follow some instuctions that I was able to found, including some from this website. I deleted and then downloaded Rust on my computer, I deleted and downloaded Eclipse, same with VS C building tools, but all this didn't help. I saw, that for some people helps to just reenter current workspace, but it was not my case. Despite this problem, default code seems to run OK, but it is almost impossible to edit. If someone had this problem or just know how to solve it, can you help please?

P.S. My English probably is not very good, so sorry for mistakes.

This is a known issue. Update to the latest proper TM4E release from https://download.eclipse.org/tm4e/releases/latest/ so that you have the bundle version with this class present.
