Struct mpeg2ts_reader::psi::DedupSectionSyntaxPayloadParser

pub struct DedupSectionSyntaxPayloadParser<SSPP> where
    SSPP: SectionSyntaxPayloadParser,  { /* fields omitted */ }

A wrapper around some other implementation of SectionSyntaxPayloadParser that passes-through section data, unless the TableSyntaxHeader indicates a version_number which is the same as the last data that was passed though.

This avoids the underlying code needing to re-parse duplicate copies of the section, which are usually inserted periodically in the Transport Stream.

Methods

impl<SSPP> DedupSectionSyntaxPayloadParser<SSPP> where
    SSPP: SectionSyntaxPayloadParser, 

pub fn new(inner: SSPP) -> DedupSectionSyntaxPayloadParser<SSPP>

Wraps the given SectionSyntaxPayloadParser in a new DedupSectionSyntaxPayloadParser instance.

Trait Implementations

impl<SSPP> SectionSyntaxPayloadParser for DedupSectionSyntaxPayloadParser<SSPP> where
    SSPP: SectionSyntaxPayloadParser, 

type Context = SSPP::Context

The type of the context object passed to all methods

fn start_syntax_section<'a>(
    &mut self,
    ctx: &mut Self::Context,
    header: &SectionCommonHeader,
    table_syntax_header: &TableSyntaxHeader<'a>,
    data: &'a [u8]
)

NB the data buffer passed to will include the bytes which are represented by header and table_syntax_header (in order that the called code can check any CRC that covers the whole section).

fn continue_syntax_section<'a>(
    &mut self,
    ctx: &mut Self::Context,
    data: &'a [u8]
)

may be called to pass the implementation additional slices of section data, if the complete section was not already passed.

fn reset(&mut self)

called if there is a problem in the transport stream that means any in-progress section data should be discarded.
