Struct CarryOverExtractor 

pub struct CarryOverExtractor { /* private fields */ }

Stateful UP extractor that carries partial user packets across BBFrame boundaries — a single UP can span multiple frames, especially in HEM where stride=187 bytes.

Use feed_nm / feed_hem per received frame; the returned Vec holds whichever 188-byte TS packets completed during that frame.

Implementations

impl CarryOverExtractor

pub fn new() -> Self

Create a fresh extractor with no carried-over state.

pub fn feed_hem( &mut self, bbheader_bytes: &[u8; 10], data_field: &[u8], npd: bool, ) -> Vec<[u8; 188]>

Feed a HEM BBFrame’s header + data field. Returns any TS packets that completed during this frame.

npd is the MATYPE-1 NPD flag for the frame — when true the stream would additionally carry DNP bytes between UPs. NPD reinsertion is NOT YET implemented here; callers must not pass npd=true until the DNP path lands.

pub fn feed_nm( &mut self, bbheader_bytes: &[u8; 10], data_field: &[u8], ) -> Vec<[u8; 188]>

Feed an NM BBFrame. Stride=188, byte[0] of each UP is the CRC-8 of the previous UP and gets replaced with 0x47.

Trait Implementations

impl Default for CarryOverExtractor

fn default() -> Self

Returns the “default value” for a type.
