Struct T2TimestampPayload 

pub struct T2TimestampPayload {
    pub bw: Bandwidth,
    pub seconds_since_2000: u64,
    pub subseconds: u32,
    pub utco: u16,
}

DVB-T2 timestamp payload (type 0x20) per ETSI TS 102 773 §5.2.7.

Layout (88 bits = 11 bytes):

• byte 0 [7:4]: rfu (4 bits) — must be 0
• byte 0 [3:0]: bw (4 bits) — Table 3
• bytes 1-5: seconds_since_2000 (40 bits)
• subseconds (27 bits): bytes 6-8 + byte 9 [7:5]
• utco (13 bits): byte 9 [4:0] + byte 10 — UTC offset in seconds

Civil UTC conversion (applying the utco leap-second offset) is intentionally not provided yet; utco is exposed as a field. emission_offset is in the timestamp’s own time base relative to 2000-01-01T00:00:00.

Fields

bw: Bandwidth

Bandwidth (determines Tsub units).

seconds_since_2000: u64

Seconds since 2000-01-01T00:00:00Z. 0 = relative timestamp. If all bits are 1 along with subseconds + utco, this is a Null timestamp.

subseconds: u32

Subsecond count (27 bits).

utco: u16

UTC offset in seconds (e.g. 34 for leap seconds as of 2016).

Implementations

impl T2TimestampPayload

pub fn is_null(&self) -> bool

Returns true if this is a Null timestamp (all bits of seconds_since_2000, subseconds, and utco are 1).

pub fn is_relative(&self) -> bool

Returns true if this is a relative timestamp (seconds_since_2000 is 0 and is not null).

pub fn emission_offset(&self) -> Option<Duration>

Time elapsed since 2000-01-01T00:00:00 in the timestamp’s own time base.

Returns None for a Null timestamp.

Civil UTC conversion (applying the utco leap-second offset) is intentionally not provided yet; utco is exposed as a field.

pub fn set_emission_offset(&mut self, offset: Duration) -> Result<(), Error>

Set seconds_since_2000 and subseconds from a core::time::Duration using the current bw. Leaves bw and utco unchanged.

Errors

Returns ReservedBitsViolation if the duration exceeds the 40-bit seconds or 27-bit subseconds range.

Trait Implementations

impl Clone for T2TimestampPayload

fn clone(&self) -> T2TimestampPayload

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for T2TimestampPayload

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

Formats the value using the given formatter.

impl Eq for T2TimestampPayload

impl<'a> From<T2TimestampPayload> for AnyPayload<'a>

fn from(p: T2TimestampPayload) -> Self

Converts to this type from the input type.

impl<'a> Parse<'a> for T2TimestampPayload

type Error = Error

The error type this implementer returns. Typically the enclosing crate’s Error enum.

fn parse(bytes: &'a [u8]) -> Result<Self, Error>

Parse bytes as Self. Returns Err(Self::Error) on any protocol violation or buffer underrun.

impl PartialEq for T2TimestampPayload

fn eq(&self, other: &T2TimestampPayload) -> 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> PayloadDef<'a> for T2TimestampPayload

const PACKET_TYPE: u8 = 0x20

Wire packet_type byte (TS 102 773 Table 1) this type accepts.

const NAME: &'static str = "TIMESTAMP"

Diagnostic name. Convention (workspace-wide): SCREAMING_SNAKE, suffix-free — BBFRAME, L1_CURRENT, FEF_NULL (no _payload suffix).

impl Serialize for T2TimestampPayload

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 T2TimestampPayload

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, Error>

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.
