Struct DefaultEngine 

pub struct DefaultEngine(/* private fields */);

Engine that selects the best available engine at runtime.

Implementations

impl DefaultEngine

pub fn new() -> Self

Creates new DefaultEngine by choosing and initializing the underlying engine.

On x86(-64) the engine is chosen in the following order of preference:

1. Avx512 (requires GFNI)
2. Avx2
3. Scalar

On AArch64 the engine is chosen in the following order of preference:

1. Neon
2. Scalar

Trait Implementations

impl Default for DefaultEngine

fn default() -> Self

Returns the “default value” for a type.

impl Engine for DefaultEngine

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)

Multiply every field element in x by the field element with logarithm log_m.

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

Replace erasures with its XOR convolution against the field logarithm table.
