def dump(value)
  value.to_s unless value.nil?
end

#load(value) ⇒ Object

We don’t want this to be called, but the Model::Property calls this one first before calling #set! on this instance again with the value returned here. Hopefully this is the only place this happens. Therefore, we just return value unchanged and take care of casting in load2

#typecast_to_primitive(value) ⇒ GURN

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

Parameters:

  • value (Hash, #to_mash, #to_s) —

    value to be typecast

Returns:

  • (GURN) —
