Hi guys, I am learning rust but i am using vscode with rust analyzer
for that.
I followed some guides to Work with rust in emacs but i dont quite
like mostly because of the inline error check

Is there a way to make emacs behave like rust-analyzer from vscode
with the full inline error ?

I write Rust professionally using Emacs. This is my entire config for
Rust:


    (use-package rust-mode
      :ensure t
      :mode "\\.rs$"
      :config
      (setq rust-format-on-save t)
      (add-hook 'rust-mode-hook 'cargo-minor-mode)
      :custom-face
      (rust-question-mark-face ((t (:inherit font-lock-builtin-face
:foreground "#ff0000" :weight bold)))))


    (use-package cargo
      :ensure t
      :defer t
      :diminish cargo-minor-mode)

    (use-package eglot
      :ensure t
      :hook
      ((go-mode . eglot-ensure)
       (rust-mode . eglot-ensure)))

Make sure that `rust-analyzer` is in your PATH and that gives a pretty
decent out-of-the-box experience.

I have the squiggly lines, but not the explanation in the buffer
itself—the error message is displayed in the echo area.
