Struct CaDescriptor 

pub struct CaDescriptor<'a> {
    pub ca_system_id: u16,
    pub ca_pid: u16,
    pub private_data: &'a [u8],
}

Conditional Access Descriptor.

Carried in the program-level or ES-level descriptor loops of a PMT, or in the CAT. Identifies the CA system and the PID where Entitlement Control Messages (ECMs) or Entitlement Management Messages (EMMs) can be found.

Fields

ca_system_id: u16

Conditional Access System ID.

Well-known CAIDs: 0x0100 Seca/Mediaguard 0x0500 Viaccess 0x0600 Irdeto 0x0B00 Conax 0x0D00 Cryptoworks 0x0E00 PowerVu 0x0F00 Tandberg/Clear 0x1700 Nagravision 2 0x1800 Nagravision 3 0x2600 BISS

ca_pid: u16

PID carrying ECM/EMM data for this CA system. Bits [12:0] of the 2-byte field; upper 3 bits are reserved.

private_data: &'a [u8]

Optional private data following the standard CA descriptor fields.

Trait Implementations

impl<'a> Clone for CaDescriptor<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for CaDescriptor<'a>

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

Formats the value using the given formatter.

impl<'a> Descriptor<'a> for CaDescriptor<'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 CaDescriptor<'a>

const TAG: u8 = TAG

Wire descriptor_tag.

const NAME: &'static str = "CA"

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

impl<'a> Eq for CaDescriptor<'a>

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

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

Converts to this type from the input type.

impl<'a> Parse<'a> for CaDescriptor<'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 CaDescriptor<'a>

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

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 CaDescriptor<'a>

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
