Subject: Subtype or derived type?

Message-ID: <orauq5$9tv$1@gioia.aioe.org> (raw)
While developing (thick object oriented) bindings for a C library:
I have developed a package containing Term_Type type with bindings
for raptor_term type:
https://github.com/vporton/redland-bindings/blob/ada2012/ada/src/rdf-raptor-term.ads
Term_Type represents pointer C type raptor_term* (where raptor_term
is a struct).
Now I am developed bindings for librdf_node which is defined as:
typedef raptor_term librdf_node;
Now I ask advice how to define the type representing librdf_node*
pointer type.
I have two variants in mind:
1.
subtype Node_Type is Term_Type;
2.
type Node_Type is new Term_Type;
Please advise which of the two is better.
