Struct ComponentDescriptor 

pub struct ComponentDescriptor<'a> {
    pub stream_content_ext: u8,
    pub stream_content: u8,
    pub component_type: u8,
    pub component_tag: u8,
    pub language_code: LangCode,
    pub text: DvbText<'a>,
}

Component Descriptor.

Fields

stream_content_ext: u8

4-bit stream_content_ext (high nibble) — combines with stream_content to identify the component (EN 300 468 §6.2.8 Table 25).

stream_content: u8

4-bit stream_content (0x01 video, 0x02 audio, 0x03 teletext, …).

component_type: u8

component_type byte (sub-classification inside the stream_content).

component_tag: u8

component_tag for cross-reference with stream_identifier_descriptor.

language_code: LangCode

ISO 639-2 language code.

text: DvbText<'a>

DVB Annex-A encoded text label for this component.

Trait Implementations

impl<'a> Clone for ComponentDescriptor<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for ComponentDescriptor<'a>

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

Formats the value using the given formatter.

impl<'a> Descriptor<'a> for ComponentDescriptor<'a>

const TAG: u8 = TAG

Descriptor tag byte — the wire identifier.

fn descriptor_length(&self) -> u8

Length of the payload portion (NOT including the 2 header bytes).

impl<'a> DescriptorDef<'a> for ComponentDescriptor<'a>

const TAG: u8 = TAG

Wire descriptor_tag.

const NAME: &'static str = "COMPONENT"

Diagnostic name. Convention (workspace-wide): SCREAMING_SNAKE, suffix-free — SHORT_EVENT, EXTENSION, NETWORK_NAME (no _descriptor suffix).

impl<'a> Eq for ComponentDescriptor<'a>

impl<'a> From<ComponentDescriptor<'a>> for AnyDescriptor<'a>

fn from(d: ComponentDescriptor<'a>) -> Self

Converts to this type from the input type.

impl<'a> Parse<'a> for ComponentDescriptor<'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 ComponentDescriptor<'a>

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

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 ComponentDescriptor<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
