Struct FecCode 

pub struct FecCode { /* private fields */ }

Reed-Solomon FEC code used by WFB blocks.

Implementations

impl FecCode

pub fn new(k: usize, n: usize) -> Result<Self, FecError>

Create an FEC code with k primary fragments and n-k parity fragments.

pub const fn k(&self) -> usize

Return the number of primary fragments.

pub const fn n(&self) -> usize

Return the total number of primary plus parity fragments.

pub fn encode( &self, primary: &[Vec<u8>], block_size: usize, ) -> Result<Vec<Vec<u8>>, FecError>

Generate parity fragments for a full primary block.

pub fn recover_primary( &self, fragments: &mut [Option<Vec<u8>>], block_size: usize, ) -> Result<usize, FecError>

Recover missing primary fragments in-place.

pub fn recover_primary_into( &self, fragments: &mut [u8], present: &mut [bool], block_size: usize, ) -> Result<usize, FecError>

Recover missing primary fragments into caller-owned reusable buffers.

present identifies received fragments. fragments contains exactly n * block_size contiguous bytes in fragment-index order. This avoids allocating recovered fragments in the packet-processing hot path.

Trait Implementations

impl Clone for FecCode

fn clone(&self) -> FecCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FecCode

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