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: feed.rb
    path of file: ./repos/fixer/gem/lib/fixer
    
    the code of the file until where you have to start completion: # frozen_string_literal: true

require 'net/http'
require 'rexml/document'

module Fixer
  # Wraps ECB's data feed
  class Feed
    include Enumerable

    SCOPES = {
      current: 'daily',
      ninety
    
    def each
      REXML::XPath.each(document, '/gesmes:Envelope/Cube/Cube[@time]') do |day|
        date = Date.parse(day.attribute('time').value)
        REXML::XPath.each(day, './Cube') do |currency|
          yield(
            date: date,
            iso_code: currency.attribute('currency').value,
            rate: Float(currency.attribute('rate').value)
          )
        end
      end
    end
