Struct Cat 

pub struct Cat<'a> {
    pub version_number: u8,
    pub current_next_indicator: bool,
    pub section_number: u8,
    pub last_section_number: u8,
    pub descriptors: DescriptorLoop<'a>,
}

Conditional Access Table.

Fields

version_number: u8

5-bit version_number from the section header.

current_next_indicator: bool

current_next_indicator bit.

section_number: u8

section_number in the sub-table sequence (typically 0 — single-section).

last_section_number: u8

last_section_number (typically 0).

descriptors: DescriptorLoop<'a>

Descriptor loop (byte 8 → CRC), preserved verbatim. ISO/IEC 13818-1 §2.4.4.6 permits descriptors other than CA in this loop; keeping the loop raw makes parse → serialize identity hold for all of them. Serializes as the typed descriptor sequence; .raw() yields the wire bytes. Use Cat::ca_descriptors for the typed CA (tag 0x09) view.

Implementations

impl<'a> Cat<'a>

pub fn ca_descriptors(&self) -> Vec<CatCaEntry>

Typed view of the CA descriptors (tag 0x09) in the descriptor loop. Non-CA descriptors are skipped; a truncated trailing descriptor ends the walk.

Trait Implementations

impl<'a> Clone for Cat<'a>

fn clone(&self) -> Cat<'a>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Cat<'a>

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

Formats the value using the given formatter.

impl<'a> Default for Cat<'a>

fn default() -> Cat<'a>

Returns the “default value” for a type.

impl<'a> Eq for Cat<'a>

impl<'a> From<Cat<'a>> for AnyTable<'a>

fn from(t: Cat<'a>) -> Self

Converts to this type from the input type.

impl<'a> Parse<'a> for Cat<'a>

type Error = Error

The error type this implementer returns. Typically the enclosing crate’s Error enum.

fn parse(bytes: &'a [u8]) -> Result<Self>

Parse bytes as Self. Returns Err(Self::Error) on any protocol violation or buffer underrun.

impl<'a> PartialEq for Cat<'a>

fn eq(&self, other: &Cat<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Cat<'_>

type Error = Error

The error type this implementer returns (usually the same as the corresponding Parse impl, but need not be).

fn serialized_len(&self) -> usize

Number of bytes serialize_into will write.

fn serialize_into(&self, buf: &mut [u8]) -> Result<usize>

Write the serialised form into buf. Returns the number of bytes written (always equal to serialized_len()).

fn to_bytes(&self) -> Vec<u8>

where Self::Error: Debug,

Convenience: allocate a Vec and serialise into it. Panics only if serialize_into misreports serialized_len() — a contract every implementer is responsible for upholding.

impl<'a> Serialize for Cat<'a>

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a> StructuralPartialEq for Cat<'a>

impl<'a> Table<'a> for Cat<'a>

const TABLE_ID: u8 = TABLE_ID

Expected table_id for this table.

const PID: u16 = PID

PID on which this table is typically carried.

impl<'a> TableDef<'a> for Cat<'a>

const TABLE_ID_RANGES: &'static [(u8, u8)]

Inclusive (lo, hi) table_id ranges this type parses.

const NAME: &'static str = "CONDITIONAL_ACCESS"

Spec name for diagnostics. SCREAMING_SNAKE, suffix-free: PROGRAM_ASSOCIATION, EVENT_INFORMATION, SERVICE_DESCRIPTION.

impl<'a> Yokeable<'a> for Cat<'static>

type Output = Cat<'a>

This type MUST be Self with the 'static replaced with 'a, i.e. Self<'a>

fn transform(&'a self) -> &'a Self::Output

This method must cast self between &'a Self<'static> and &'a Self<'a>.

fn transform_owned(self) -> Self::Output

This method must cast self between Self<'static> and Self<'a>.

unsafe fn make(this: Self::Output) -> Self

This method can be used to cast away Self<'a>’s lifetime.

fn transform_mut<F>(&'a mut self, f: F)

where F: 'static + for<'b> FnOnce(&'b mut Self::Output),

This method must cast self between &'a mut Self<'static> and &'a mut Self<'a>, and pass it to f.
