iTerm 2 beta 3.0 find exact line and column of error in Rust and go to error in Vim

gistfile1.txt

iTerm:
  Trigger regex: ^([a-zA-Z0-9+/.-]+):([0-9]+):([0-9]+): ([0-9]+):[0-9]+ (?:error):
  Trigger action: Capture Output
  Trigger parameter: echo ":call GetTabOrOpenFile(\"\1\")"; echo "$[\2 - 1]G\3|"

For .vimrc:
  set swb=usetab
  function! GetTabOrOpenFile(file)
    try
      execute "tab sb ".a:file
    catch /^Vim\%((\a\+)\)\=:E94/   
      execute "tabnew"
      execute "e ".a:file
      " execute "tabe ".a:file
    endtry
    1
  endfunction
  
Put this in .zshrc to make suspending Vim easier, but it's not required:
  fancy-ctrl-z () {
    if [[ $#BUFFER -eq 0 ]]; then
      BUFFER="fg"
      zle accept-line
    else
      zle push-input
      zle clear-screen
    fi
  }
  zle -N fancy-ctrl-z
  bindkey '^Z' fancy-ctrl-z


How to use it:
  Press shift+cmd+b to show toolbox
  Build a Rust project
  See the errors come up in Capture Output in toolbox
  Open Vim
  Double-click error
