  dto_obj = new(attrs || kwargs)
  set_attrs = attrs ? attrs.keys : kwargs.keys
  fields_to_set = fields_with_default.reject{ set_attrs.include?(_1.name) }

  dto_obj
end

#build_from_attrs(attrs) ⇒ Object

Fast-path constructor used by compiled db_load: takes ownership of attrs (it becomes @_attrs without copying), so callers must not reuse the hash. Reads @fields_with_default directly: the contract-wrapped reader would revalidate the array on every row.
