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: label.rb
    path of file: ./repos/activegraph/lib/active_graph/core
    
    the code of the file until where you have to start completion: module ActiveGraph
  module Core
    class Label
      attr_reader :name
      delegate :version?, to: ActiveGraph::Base

      def initialize(name)
        @name = name
      end

      def create_index(*properties, **options)
        validate_index_options!(options)
        if version?('>=4.4')
          
    
        def drop_constraints
          result = ActiveGraph::Base.read_transaction do |tx|
            tx.run(ActiveGraph::Base.version?('<4.3') ? 'CALL db.constraints' : 'SHOW CONSTRAINTS YIELD *').to_a
          end
          ActiveGraph::Base.write_transaction do |tx|
            result.each do |record|
              tx.run("DROP #{record.keys.include?(:name) ? "CONSTRAINT #{record[:name]}" : record[:description]}")
            end
          end
        end
