Struct Ssse3

pub struct Ssse3 { /* private fields */ }

Optimized Engine using SSSE3 instructions.

Ssse3 is an optimized engine that follows the same algorithm as NoSimd but takes advantage of the x86 SSSE3 SIMD instructions.

Implementations

impl Ssse3

pub fn new() -> Self

Creates new Ssse3, initializing all tables needed for encoding or decoding.

Currently only difference between encoding/decoding is LogWalsh (128 kiB) which is only needed for decoding.

Trait Implementations

impl Clone for Ssse3

fn clone(&self) -> Ssse3

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for Ssse3

fn default() -> Self

Returns the “default value” for a type.

impl Engine for Ssse3

fn fft( &self, data: &mut ShardsRefMut<'_>, pos: usize, size: usize, truncated_size: usize, skew_delta: usize, )

In-place decimation-in-time FFT (fast Fourier transform).

fn ifft( &self, data: &mut ShardsRefMut<'_>, pos: usize, size: usize, truncated_size: usize, skew_delta: usize, )

In-place decimation-in-time IFFT (inverse fast Fourier transform).

fn mul(&self, x: &mut [[u8; 64]], log_m: GfElement)

x[] *= log_m

fn eval_poly(erasures: &mut [GfElement; 65536], truncated_size: usize)
