How to display indentation in vim?

How to display indentation in vim, like here

These options did not help

set list
set lcs=tab:\|\  " the last character is space!

I opened another file in vim - and a miracle, the indents are displayed.

Only you can see that it's all about the settings, such as set tabstop and so on.
I would like line breaks to be visible as well.
I will be glad to help.

Answer 1

Issue resolved.
Such settings in the .vimrc file helped

set tabstop=2			 " To match the sample file
set noexpandtab		 " Use tabs, not spaces
%retab!						 " Retabulate the whole file
