Struct Cit 

pub struct Cit<'a> {
    pub private_indicator: bool,
    pub service_id: u16,
    pub version_number: u8,
    pub current_next_indicator: bool,
    pub section_number: u8,
    pub last_section_number: u8,
    pub transport_stream_id: u16,
    pub original_network_id: u16,
    pub prepend_strings: &'a [u8],
    pub crid_entries: &'a [u8],
}

Content Identifier Table (ETSI TS 102 323 v1.4.1 §12.2).

Variable-length fields are kept as raw byte slices borrowing from the source buffer. Callers that need to iterate CRID entries may walk crid_entries directly per the wire format:

for each entry:
  crid_ref             (2 bytes, u16 big-endian)
  prepend_string_index (1 byte)
  unique_string_length (1 byte)
  unique_string_bytes  (unique_string_length bytes)

Fields

private_indicator: bool

private_indicator bit from byte 1.

service_id: u16

service_id — identifies the container this section belongs to (table_id_extension, bytes 3-4).

version_number: u8

5-bit version_number.

current_next_indicator: bool

current_next_indicator bit.

section_number: u8

Section counter within the sub-table.

last_section_number: u8

Final section number in the sub-table.

transport_stream_id: u16

transport_stream_id of the carrying TS.

original_network_id: u16

original_network_id of the originating network.

prepend_strings: &'a [u8]

Raw prepend-string block. The wire prepend_strings_length byte is derived from prepend_strings.len() on serialize (≤ 255). Entries are null-terminated ASCII/DVB-text fragments; addressed by index from the CRID loop.

crid_entries: &'a [u8]

Raw CRID entry loop (everything between the prepend-string block and the CRC-32). Walk per the format documented on the struct.

Trait Implementations

impl<'a> Clone for Cit<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for Cit<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for Cit<'a>

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

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

Converts to this type from the input type.

impl<'a> Parse<'a> for Cit<'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 Cit<'a>

fn eq(&self, other: &Cit<'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 Cit<'_>

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 Cit<'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 Cit<'a>

impl<'a> Table<'a> for Cit<'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 Cit<'a>

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

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

const NAME: &'static str = "CONTENT_IDENTIFIER"

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

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

type Output = Cit<'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.
