Module ci_plus 

CI Plus extensions (ETSI TS 103 205) — the resource-scoped APDU layer.

Like the TS 101 699 extensions (crate::ci_ext), the CI Plus resources defined by TS 103 205 have their own apdu_tag namespace that collides with EN 50221 and TS 101 699 — e.g. the Multi-stream resource’s tags live in 0x9F92xx, Content Control’s in 0x9F90xx, and the extended CA Support ca_pmt/ca_pmt_reply reuse EN 50221’s 0x9F8032/0x9F8033 verbatim. The same tag bytes therefore denote different objects depending on which resource’s session they arrive on, so they cannot join the global crate::AnyApdu. This module provides a resource-scoped dispatch (CiPlusApdu): parsing keys on the resource_identifier() first (classify), then the leading apdu_tag selects the object within that resource.

Spec: ETSI TS 103 205 V1.4.1 — resource IDs in docs/ts_103_205/resource-ids.md; per-resource layouts cited in their own module docs.

Resources implemented this pass

• Multi-stream (0x00900041, multistream) — CICAM_multistream_capability / PID_select_req / PID_select_reply.
• Content Control multi-stream (0x008C1041, content_control) — the printed-syntax extended APDUs cc_PIN_reply / cc_PIN_event, plus the SAC protocol datatype model.
• Multi-stream Host Control (0x00200081, base v3 0x00200043, multistream_host_control) — the tune APDUs tune_triplet_req / tune_lcn_req / tune_ip_req / tuner_status_req / tuner_status_reply. Both resource ids route to the same CiPlusResource::MultistreamHostControl kind, carrying the multistream_host_control::HostControlMode that selects the tune_ip_req reserved-bit budget. tune_broadcast_req / tune_reply / ask_release(_reply) are deferred to CI Plus V1.3 and not encoded.
• Sample decryption (0x00920041, sample_decryption) — sd_info_req / sd_info_reply / sd_start(_reply) / sd_update(_reply), with opaque DRM metadata / UUID payloads.
• CICAM Player (0x00930041, cicam_player) — the full 16-APDU set 9FA000–9FA00F (CICAM_player_verify_req … CICAM_player_update_reply).
• Auxiliary File System / file retrieval (0x00910041, file_retrieval) — FileSystemOffer / FileSystemAck, plus FileRequest / FileAcknowledge whose bodies defer to CI Plus V1.3 (carried opaquely; tags only established).

Not dispatched here

• CA Support multi-stream (ca_support) — TS 103 205 does not print a resource_id for the resource_type = 2 variant (it defers to CI Plus V1.3), so its extended ca_pmt/ca_pmt_reply are standalone typed structs, directly constructible/parseable but not wired into CiPlusApdu.
• Low-Speed Comms v4 extensions (low_speed_comms_v4) — TS 103 205 §10 prints no LSC v4 resource_id (the LSC resource_id + base comms_* APDUs defer to CI Plus V1.3), so the v4 comms_info / comms_IP_config APDUs and the hybrid/multicast descriptors are standalone typed structs (tag-dispatch helper), not wired into CiPlusApdu.
• URI v3 (uri) — the uri_message is a SAC datatype (datatype_id 25), not an APDU/resource, so uri::UriMessage is a standalone typed struct used from the Content Control SAC layer.
• CI Plus descriptors (descriptors) — Sample-Mode TLV descriptors, not APDUs, so they are standalone too.

Enums

CiPlusApdu

A parsed CI Plus APDU, scoped to the resource it arrived on.

CiPlusResource

The CI Plus resource a ResourceId denotes, for the resources dispatched by CiPlusApdu. Returns None for any other resource (including the deferred-resource_id CA Support multi-stream type).

Constants

HOST_CONTROL_V3
