Validation rule for 2 fields unique

In my laravel 5.6 application I use next rule to check unique for name field

    'name' => [
        'required',
        'string',
        'max:255',
        Rule::unique('votes')->ignore($vote_id),
    ],

I use ignore condition to update this vote.

But I have a table where field “name” is unique inside of any "vote_id" :

CREATE TABLE "vote_items" 
  "id" integer not null primary key autoincrement, 
  "vote_id" integer null, 
  "name" varchar not null, 

Can I use unique checks condition in such cases and if yes which syntax is correct?

Thanks!
