Struct TeletextDataField 

pub struct TeletextDataField {
    pub header: LineHeader,
    pub framing_code: u8,
    pub txt_data_block: [u8; 42],
}

EBU / Inverted Teletext data field — ETSI EN 301 775 §4.5.1, Table 4 (data_unit_id 0x02, 0x03, 0xC0).

The txt_data_block (42 bytes) is the EN 300 706 magazine_and_packet_address and data_block following the clock-run-in/framing-code; EN 300 706 decoding is out of scope, so it is held opaquely.

Fields

header: LineHeader

Shared first-byte header: reserved_future_use 11 | field_parity | line_offset.

framing_code: u8

8-bit framing_code (0b11100100 EBU / 0b00011011 Inverted, §4.5.2).

txt_data_block: [u8; 42]

42-byte txt_data_block (336 bits, §4.5; EN 300 706 — opaque here).

Implementations

impl TeletextDataField

pub fn serialized_len(&self) -> usize

Bytes this data field occupies (the data_unit_length).

pub fn parse(data: &[u8]) -> Result<Self>

Parse exactly one Teletext data field from data (data must be the data-unit body of data_unit_length bytes).

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

Serialize into out, returning the number of bytes written.
