Taglist-like Vim plugin for Rust?

Does anyone know of a Vim plugin similar to taglist for Rust?
Taglist is a source code browser that opens in a side pane. It shows classes, methods, and other declarations.
It’s useful for having an overview, especially of larger projects consisting of multiple files.

I know of racer-vim but it provides jump-to-definition and jump-to-help but not this. There’s also rusty-tags however I was unable to get its output to work with taglist in vim.

I’ve been using tagbar, but it’s not ideal either for rust. What we really need is a good etags implementation for rust.


ya that would be great
I’ve went with NERDTree for now, at least having a file list of the project gives me some overview, together with racer’s jump-to-definition it’s more or less convenient
should probably switch to a real IDE at some point but doesn’t really like something closed-source or overly heavy

The primary reasons I use vim are (1) convenience… I’m already in the terminal and I don’t want to switch to another window; (2) keyboard-oriented: I don’t like using mice; and (3) it’s already installed on most linux/macos boxes. I don’t think any IDE will ever have those features in the near-term…

Really, my rust/vim setup is pretty nice. The only thing missing is something like etags/tagbar/taglist.


More or less all the same reasons for me!

Just at times like this, hunting plugins, I wonder if I’m not spending too much time fighting my editor. Overall it’s nice though and I’m very used to it.

What's not ideal about tagbar? Works great for me.

thanks a lot for the suggestions @mark-i-m @stjepang @lkurusa will check them out!

Edit: looks like tagbar was exactly what I was looking for; the difference with taglist is that it shows only the tags for the current file and not for the entire project, but that’s ok as I have a tree browser too now.

I will try that out @stjepang! Thanks :slight_smile:

@lkurusa If you have used tagbar with C++, you will note the difference :wink:

Just noticed that if a recent version of rust-vim plugin is installed, the changes to ~/.ctags and g:tagbar_type_rust are unnecessary—will even result in every tag being shown twice

I had a similar problem with Tagbar, but it turns out that universal-ctags has better native Rust support and this can be integrated with Tagbar in a nice way.

  1. Build and install universal-ctags
  2. Put the following in your .vimrc:
let g:rust_use_custom_ctags_defs = 1
let g:tagbar_type_rust = {
  \ 'ctagsbin' : '/path/to/your/universal/ctags',
  \ 'ctagstype' : 'rust',
  \ 'kinds' : [
      \ 'n:modules',
      \ 's:structures:1',
      \ 'i:interfaces',
      \ 'c:implementations',
      \ 'f:functions:1',
      \ 'g:enumerations:1',
      \ 't:type aliases:1:0',
      \ 'v:constants:1:0',
      \ 'M:macros:1',
      \ 'm:fields:1:0',
      \ 'e:enum variants:1:0',
      \ 'P:methods:1',
  \ ],
  \ 'sro': '::',
  \ 'kind2scope' : {
      \ 'n': 'module',
      \ 's': 'struct',
      \ 'i': 'interface',
      \ 'c': 'implementation',
      \ 'f': 'function',
      \ 'g': 'enum',
      \ 't': 'typedef',
      \ 'v': 'variable',
      \ 'M': 'macro',
      \ 'm': 'field',
      \ 'e': 'enumerator',
      \ 'P': 'method',
  \ },
\ }
  1. Restart vim and enjoy!



Thanks, that’s a great setup, so much more detailed than the default tagbar one.

@tmandry You made my day!


How to make it show which trait is being implemented?

For impl Foo for Bar it shows just “Bar: implementation”, having “Foo” there would be helpful.
