Convert the data held in this object to a structure (eg,

These structures may be primitive Python types (string,
integer, boolean, etc.) or complex Python types (lists,
tuples, or dicts). If the return type is a dict, then the keys
of the dict match the fieldname of the object. If the return
struct (or value of a dict key) is a list, then it is a list
of structs. Otherwise, the struct is just the value of the
attribute.
