def self.dump(object, options = {})
  if defined? MultiJson
    MultiJson.dump(object, options)
  else
    options.merge!(::JSON::PRETTY_STATE_PROTOTYPE.to_h) if options.delete(:pretty)
    object.to_json(options)

.load(string, options = {}) ⇒ Object

These methods do similar processing to the fallback implemented by MultiJson when using the built-in JSON backend, to ensure consistent behavior whether or not MultiJson can be loaded.
