Struct CableDeliverySystemDescriptor 

pub struct CableDeliverySystemDescriptor {
    pub frequency_bcd: u32,

    pub fec_inner: FecInner,
}

Cable Delivery System Descriptor.

Fields

frequency_bcd: u32

32-bit BCD frequency in 100 kHz (e.g. 0x03460000 = 346.0000 MHz).

fec_outer: FecOuter

FEC outer coding scheme.

modulation: Modulation

Modulation scheme.

symbol_rate_bcd: u32

28-bit BCD symbol rate in Msym/s (value stored in low 28 bits of u32).

fec_inner: FecInner

FEC inner code rate.

Implementations

impl CableDeliverySystemDescriptor

pub fn frequency_hz(&self) -> Option<u64>

Decode the 32-bit BCD frequency to Hz (100 Hz field resolution). None if the BCD nibbles are out of range.

e.g. 0x0346_0000 → 346_000_000 Hz (346.0000 MHz).

pub fn set_frequency_hz(&mut self, hz: u64) -> Result<()>

Set frequency from Hz, encoding to the 8-digit BCD field at the field’s 100 Hz resolution (finer precision is truncated).

Errors

ValueOutOfRange on overflow of the 8-digit BCD field.

pub fn symbol_rate_sps(&self) -> Option<u64>

Decode the 28-bit BCD symbol_rate to symbols/second (100 sym/s resolution). None if the BCD nibbles are out of range.

pub fn set_symbol_rate_sps(&mut self, sps: u64) -> Result<()>

Set symbol_rate from symbols/second (100 sym/s field resolution).

Errors

ValueOutOfRange on overflow of the 7-digit BCD field.

Trait Implementations

impl Clone for CableDeliverySystemDescriptor

fn clone(&self) -> CableDeliverySystemDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CableDeliverySystemDescriptor

impl Debug for CableDeliverySystemDescriptor

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

Formats the value using the given formatter.

impl DescriptorDef<'_> for CableDeliverySystemDescriptor

const TAG: u8 = TAG

Wire descriptor_tag.

const NAME: &'static str = "CABLE_DELIVERY_SYSTEM"

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

impl Eq for CableDeliverySystemDescriptor

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

fn from(d: CableDeliverySystemDescriptor) -> Self

Converts to this type from the input type.

impl<'a> Parse<'a> for CableDeliverySystemDescriptor

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 PartialEq for CableDeliverySystemDescriptor

fn eq(&self, other: &CableDeliverySystemDescriptor) -> 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 CableDeliverySystemDescriptor

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 CableDeliverySystemDescriptor

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.
