Struct BBHeader 

pub struct BBHeader<'a>(/* private fields */);

DVB-S2 BBHEADER.

This struct is used to parse the fields of a BBHEADER. It is simply a wrapper over an array reference &[u8; 10].

Implementations

impl BBHeader<'_>

pub const LEN: usize = 10usize

Length of a BBHEADER in bytes.

pub fn new(data: &[u8; 10]) -> BBHeader<'_>

Creates a new BBHEADER.

pub fn tsgs(&self) -> TsGs

Gives the value of the TS/GS (Transport Stream Input or Generic Stream Input) field.

pub fn is_gse_hem(&self) -> bool

Returns true if the BBFRAME is a GSE-HEM BBFRAME.

GSE-HEM BBFRAMEs have a different layout and omit some fields.

pub fn sismis(&self) -> SisMis

Give the value of the SIS/MIS (Single Input Stream or Multiple Input Stream) field.

pub fn ccmacm(&self) -> CcmAcm

Gives the value of the CCM/ACM (Constant Coding and Modulation or Adaptive Coding and Modulation) field.

pub fn issyi(&self) -> bool

Gives the value of ISSY (Input Stream Synchronization Indicator) field.

pub fn npd(&self) -> bool

Gives the value of the NPD (Null-packet Deletion) field.

pub fn gse_lite(&self) -> bool

Gives the value of the GSE-Lite field.

This field is used in DVB-S2X only and replaces the NPD field in GSE modes.

pub fn rolloff(&self) -> RollOff

Gives the value of the roll-off (RO) field.

pub fn isi(&self) -> u8

Gives the value of the ISI (Input Stream Identifier) field.

This field corresponds to the MATYPE-2 byte and is only used in Multiple Input Stream mode.

pub fn upl(&self) -> Option<u16>

Gives the value of the UPL (User Packet Length) field.

The function returns None if the UPL field is not present, which is the case in GSE-HEM mode.

pub fn issy(&self) -> Option<[u8; 3]>

Gives the value of the ISSY field.

The ISSY field is only present in GSE-HEM BBFRAMEs which have the ISSYI bit asserted. If the ISSY field is not present, this function returns None. The ISSY field is split into 2-byte field and a 1-byte field in the BBHEADER. These are concatenated into a 3-byte array in the output of this function.

pub fn dfl(&self) -> u16

Gives the value of the DFL (Data Field Length) field.

pub fn sync(&self) -> Option<u8>

Gives the value of the SYNC (User Packet Sync-byte) field.

The function returns None if the SYNC field is not present, which is the case in GSE-HEM mode.

pub fn syncd(&self) -> u16

Gives the value of the SYNCD field.

pub fn crc8(&self) -> u8

Gives the value of the CRC-8 field.

pub fn compute_crc8(&self) -> u8

Computes and returns the CRC-8 of the BBHEADER.

pub fn crc_is_valid(&self) -> bool

Checks if the CRC-8 of the BBHEADER is valid.

Trait Implementations

impl<'a> Clone for BBHeader<'a>

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> Debug for BBHeader<'a>

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

Formats the value using the given formatter.

impl Display for BBHeader<'_>

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

Formats the value using the given formatter.

impl<'a> Hash for BBHeader<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for BBHeader<'a>

fn eq(&self, other: &BBHeader<'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.
