You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: string_literals_in_interpolation.rb
    path of file: ./repos/rubocop/lib/rubocop/cop/style
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

module RuboCop
  mo
    
        def on_regexp(node); end

        private

        def message(_node)
          # single_quotes -> single-quoted
          kind = style.to_s.sub(/_(.*)s/, '-\1d')

          "Prefer #{kind} strings inside interpolations."
        end

        def offense?(node)
          # If it's not a string within an interpolation, then it's not an
          # offense for this cop.
          return false unless inside_interpolation?(node)

          wrong_quotes?(node)
        end
      end
