I've installed eglot aiming for a very lightweight and minimal lsp experience for Rust and C (basically just some autompletions and some errors shown). My configuration looks something like this:
```lisp
(use-package eglot)
(add-to-list 'eglot-server-programs '((c++-mode c-mode) "clangd"))
(add-hook 'rust-mode-hook 'eglot-ensure)
(add-hook 'c-mode-hook 'eglot-ensure)
(use-package company)
(global-company-mode)
(use-package yasnippet)
(yas-global-mode 1)
```
There're a few problems with this, though. On Rust mode, everytime I hover over a keyword, it opens like two buffers: One floating, and one on the bottom. All I want are some completions and some errors. How can I disable all the frills of eglot and rust analyzer?
