How to reproduce the issue

Enter command mode and type TAB after any Rust command followed by a space.

Example: :RustAnalyzer[space][TAB]

Expected behaviour

I would expect to see a list of available options to run the command. In the example of RustAnalyzer, they should be start and stop

Actual behaviour

I get the attached error whenever hitting the TAB key.
Manually typing the command option switch (i.e. start or stop) works fine.

The same happens with any of the RustLsp command switches.

Pressing TAB with other plugins in command mode, seems to work fine (see attached example for Trouble auto completion)

Sorry if this is an issue from my side/config. I'm just trying to move from rust-tools to your new plugin for which you deserve a big thank you!

The minimal config used to reproduce this issue.

plugins.lua

  {
  'mrcjkb/rustaceanvim',
  version = '^3', -- Recommended
  ft = { 'rust' },
    config = function(_, opts)
      require("core.utils").load_mappings("rustaceanvim")
    end
},

Hey 👋

Thanks for reporting this.
I use vim.iter in the code for tab completion, which appears to have been added in Neovim nightly.

I'll look into fixing that 😄

Thank you. It works! Much appreciated
