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: hint.rb
    path of file: ./repos/govuk-form-builder/lib/govuk_design_system_formbuilder/traits
    
    the code of the file until where you have to start completion: module GOVUKDesignSystemFormBuilder
  module Traits
    module Hint
      def hint_id
        
    
      def hint_content
        case @hint
        when Hash
          @hint
        when Proc
          { content: @hint }
        else
          fail(ArgumentError, %(hint must be a Proc or Hash))
        end
