rust types displayed in minibuffer are truncated

[Ngoguey42]

Thank you for the bug report

• I am using the latest version of lsp-mode related packages.
• I checked FAQ and Troubleshooting sections
• You may also try reproduce the issue using clean environment using the following command: M-x lsp-start-plain

Bug description

Putting the cursor on a rust variable shows the type in the minibuffer:

Recently this stopped working correctly for some types:

When I run lsp-describe-thing-at-point on this problematic type I see 2 lines:

My understanding is that only the first line is shown in the minibuffer.

Steps to reproduce

1. cargo init --name main to create a dummy project

2. open main.rs with emacs

3. answer i to the prompt that offers to import the project root

4. Add an let i = 0; line in the code.

5. Put the cursor on i and witness the problem in the minibuffer

Expected behavior

The type of the variable should be shown

I was able to mitigate this problem using (setq lsp-eldoc-render-all t)

It’s probably part of this PR/discussion #1740, which iirc didn’t get merged because the parsing/matching was too brittle and dependant on RA unspecified implementations that could change version to version
