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: country.rb
    path of file: ./repos/telephone_number/lib/telephone_number
    
    the code of the file until where you have to start completion: module TelephoneNumber
  class Country
    attr_reader :country_code, :national_prefix, :national_prefix_for_parsing,
                :national_prefix_transform_rule, :international_prefix, :formats,
                :validations, :mobile_token, :country_id, :general_validation, :main_country_for_code

    MOBILE_TOKEN_COUNTRIES = { AR: '9' }.freeze

    def initialize(data_hash)
      validations = data_hash.fetch(:validations, {}).dup
      @country_code = data_hash[:count
    
    def initialize(data_hash)
      validations = data_hash.fetch(:validations, {}).dup
      @country_code = data_hash[:country_code]
      @country_id = data_hash[:id]
      @general_validation = NumberValidation.new(:general_desc, validations[:general_desc]) if validations[:general_desc]
      @international_prefix = Regexp.new(data_hash[:international_prefix]) if data_hash[:international_prefix]
      @main_country_for_code = data_hash[:main_country_for_code] == 'true'
      @mobile_token = MOBILE_TOKEN_COUNTRIES[@country_id.to_sym]
      @national_prefix = data_hash[:national_prefix]
      @national_prefix_for_parsing = Regexp.new(data_hash[:national_prefix_for_parsing]) if data_hash[:national_prefix_for_parsing]
      @national_prefix_transform_rule = data_hash[:national_prefix_transform_rule]
      @validations = validations.delete_if { |name, _| name == :general_desc || name == :area_code_optional }
                                .map { |name, data| NumberValidation.new(name, data) }
      @formats = data_hash.fetch(:formats, []).map { |format| NumberFormat.new(format, data_hash[:national_prefix_formatting_rule]) }
    end
