Metadata Descriptor.

Fields

metadata_application_format: u16

Metadata application format (u16; Table 2-84).

metadata_application_format_identifier: Option<u32>

Metadata application format identifier — present when metadata_application_format == 0xFFFF.

metadata_format: MetadataFormat

Metadata format (Table 2-87).

metadata_format_identifier: Option<u32>

Metadata format identifier — present when metadata_format == 0xFF.

metadata_service_id: u8

Metadata service ID.

decoder_config_flags: DecoderConfigFlags

Decoder config flags (Table 2-90, 3-bit).

dsmcc_flag: bool

DSM-CC service identification flag.

service_identification: Option<&'a [u8]>

DSM-CC service identification — present when dsmcc_flag is true.

decoder_config: DecoderConfig<'a>

Decoder configuration block.

private_data: &'a [u8]

Trailing private data bytes.

Trait Implementations

impl<'a> Clone for MetadataDescriptor<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for MetadataDescriptor<'a>

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

Formats the value using the given formatter.

impl<'a> DescriptorDef<'a> for MetadataDescriptor<'a>

const TAG: u8 = TAG

Wire descriptor_tag.

const NAME: &'static str = "METADATA"

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

impl<'a> Eq for MetadataDescriptor<'a>

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

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

Converts to this type from the input type.

impl<'a> Parse<'a> for MetadataDescriptor<'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 MetadataDescriptor<'a>

fn eq(&self, other: &MetadataDescriptor<'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<'a> Serialize for MetadataDescriptor<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Serialize for MetadataDescriptor<'_>

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.

impl<'a> StructuralPartialEq for MetadataDescriptor<'a>

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

type Output = MetadataDescriptor<'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.
