Struct SourceBlockDecoder 

pub struct SourceBlockDecoder { /* private fields */ }

A struct that represents a source block decoder that uses Raptor codes.

Implementations

impl SourceBlockDecoder

pub fn new(nb_source_symbols: usize) -> Self

Create a new decoder

Arguments

• nb_source_symbols - Number of source symbols in the block

Returns

• A new SourceBlockDecoder instance

pub fn push_encoding_symbol(&mut self, encoding_symbol: &[u8], esi: u32)

Push an encoding symbol to the decoder

Arguments

• encoding_symbol - A slice of u8 numbers representing the encoding symbol data
• esi - Encoding symbol identifier (ESI)

pub fn fully_specified(&self) -> bool

Return true when the block can be fully decoded

pub fn decode(&mut self, source_block_length: usize) -> Option<Vec<u8>>

Decode the source block

Parameters

• source_block_length: The size of the source block in bytes.
• encoding_symbol_size: Size of an encoding symbol

Returns

• None if the source block cannot be decoded
• Some(Vec<u8>) if the block is decoded. The vector contains the decoded source block data
