Expand description
SPDU session layer — a sans-IO mechanism over the transport layer (ETSI EN 50221 §7.2).
Multiplexes logical sessions (one per resource in use) over the transport
connection: allocates/tracks session_nbs, answers open_session_request
for resources the host advertises, opens create_session on demand, and
routes session_number+APDU to/from the resource bound to a session. It is
mechanism only — which resources the host provides is the caller’s policy,
supplied as the provides predicate to SessionLayer::on_spdu.
