Struct ConditionalAccessTable 

pub struct ConditionalAccessTable {
    pub version_number: u8,
    pub current_next_indicator: bool,
    pub section_number: u8,
    pub last_section_number: u8,
    pub descriptors: Vec<u8>,
}

Parsed Conditional Access Table per §2.4.4.6 / Table 2-27.

The CAT carries the program-wide CA descriptor block — one or more CA_descriptors (§2.6.16) keyed by CA_system_ID that point at the EMM PIDs. The CAT is signalled on the fixed PID CAT_PID and uses table_id == CAT_TABLE_ID. Like PAT and PMT it may be segmented across multiple sections, all of which share table_id_extension (reserved; not used to identify a CAT).

Fields

version_number: u8

5-bit version_number.

current_next_indicator: bool

current_next_indicator.

section_number: u8

section_number.

last_section_number: u8

last_section_number.

descriptors: Vec<u8>

Raw bytes of the descriptor() loop carried in the CAT body — walk with Self::iter_descriptors to get typed CA entries.

Implementations

impl ConditionalAccessTable

pub fn parse(section: &[u8]) -> Result<Self, TsError>

Parse a single CAT section. The slice must run from table_id through the CRC trailer (i.e. the pointer_field has already been skipped).

pub fn iter_descriptors(&self) -> DescriptorIter<'_>

Walk the carried descriptor() loop as typed TLV records.

Trait Implementations

impl Clone for ConditionalAccessTable

fn clone(&self) -> ConditionalAccessTable

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ConditionalAccessTable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ConditionalAccessTable

fn default() -> ConditionalAccessTable

Returns the “default value” for a type.
