Struct ManagedCa 

pub struct ManagedCa { /* private fields */ }

The Driver’s owned CAS-layer state (#763 Layer 1) — one CI slot’s active service set plus the entitlement re-query cadence.

Implementations

impl ManagedCa

pub fn new() -> Self

New, empty managed-CA state at the default re-query cadence (REQUERY_DEFAULT).

pub fn services(&self) -> &BTreeMap<u16, ManagedService>

The currently-tracked services, keyed by program_number.

pub fn requery_interval(&self) -> Duration

The re-query cadence currently configured (Task 5 consumes this).

pub fn emm_pids(&self) -> &[u16]

The EMM PIDs to route into ci0: the last set_cat’s CAID → EMM-PID map, intersected with the CAM’s advertised CAIDs (last ca_info) — a CAT entry for a CAID the CAM never advertised is never fed (#763 Task 4).

pub fn descramble_pids(&self) -> &[u16]

The union of every actively-managed service’s elementary-stream PIDs — the PIDs a caller must route into ci0 for descrambling.

pub fn ca_pids(&self) -> &[u16]

The union of every actively-managed service’s CA_PIDs (ECM PIDs, ISO/IEC 13818-1 §2.6.16 CA_descriptor CA_PID, programme + ES level combined) — the control-word channel a caller must route into ci0 alongside descramble_pids; without these the module has ES to descramble but no control words to do it with.

pub fn required_pids(&self) -> Vec<u16>

descramble_pids ∪ ca_pids ∪ emm_pids ∪ PCR — every PID class a caller must route into ci0 for this slot to both descramble the tracked services (ES + ECM), keep entitlements current (EMM), and carry each active service’s programme clock reference (PCR — ISO/IEC 13818-1 §2.4.4.8). The PCR PID is folded in here rather than into descramble_pids because a dedicated PCR PID carries no elementary stream of its own; a service whose pcr_pid is 0x1FFF (“no PCR”) contributes nothing. Computed on demand (small sets); dedup + sorted.

Trait Implementations

impl Default for ManagedCa

fn default() -> Self

Returns the “default value” for a type.
