Enum DataUnitPayload 

#[non_exhaustive]
pub enum DataUnitPayload<'a> {
    Teletext(TeletextDataField),
    Vps(VpsDataField),
    Wss(WssDataField),
    ClosedCaptioning(ClosedCaptioningDataField),
    Monochrome(MonochromeDataField<'a>),
    Stuffing {
        length: u8,
    },
    Opaque(&'a [u8]),
}

The typed body of one data unit (ETSI EN 301 775 §4.4, dispatched on data_unit_id).

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Teletext(TeletextDataField)

EBU / Inverted Teletext (0x02, 0x03, 0xC0) — §4.5.

Vps(VpsDataField)

VPS (0xC3) — §4.6.

Wss(WssDataField)

WSS (0xC4) — §4.7.

ClosedCaptioning(ClosedCaptioningDataField)

Closed Captioning (0xC5) — §4.8.

Monochrome(MonochromeDataField<'a>)

Monochrome 4:2:2 luminance samples (0xC6) — §4.9.

Stuffing

Stuffing (0xFF) — §4.4.1: no data field. data_unit_length stuffing bytes follow and are discarded; their count is retained for round-trip.

Fields

length: u8

The data_unit_length (number of 0xFF stuffing bytes that follow).

Opaque(&'a [u8])

Reserved / user-defined data_unit_id whose body this crate does not interpret (Table 3: discard). The raw body bytes are retained.

Implementations

impl<'a> DataUnitPayload<'a>

pub fn serialized_len(&self) -> usize

The number of body bytes (data_unit_length) this payload serializes to.

pub fn parse(id: DataUnitId, body: &'a [u8]) -> Result<Self>

Parse a data-unit body of length bytes against its id (§4.4, Table 1 dispatch, resolved per Table 3). body must be exactly the data_unit_length bytes following the length field.

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

Serialize the body into out, returning the number of bytes written.

Trait Implementations

impl<'a> Clone for DataUnitPayload<'a>

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

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

Performs copy-assignment from source.

impl<'a> Debug for DataUnitPayload<'a>

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

Formats the value using the given formatter.

impl<'a> Eq for DataUnitPayload<'a>

impl<'a> PartialEq for DataUnitPayload<'a>

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

Equality operator ==.

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

impl<'a> Serialize for DataUnitPayload<'a>

Available on crate feature serde only.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
