Writing to a CSV with Faster::CSV

Is there a way to write a csv file using a hash instead of an array?
Something like this:

header_keys = :first_name, :last_name, :email
FasterCSV.open("path/to/file.csv", "w") do |csv|
    User.all.do |user|
       csv << user
    end
  end

Thanks...

csv << user.attributes.values_at(*header_keys)
