Struct reed_solomon_simd::engine::DefaultEngine

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

Engine that on x86 platforms at runtime chooses the best Engine.

Implementations

impl DefaultEngine

pub fn new() -> Self

Creates new DefaultEngine by chosing and initializing the underlying engine.

The engine is chosen in the following order of preference:

1. Avx2
2. Ssse3
3. NoSimd

Trait Implementations

impl Clone for DefaultEngine

fn clone(&self) -> DefaultEngine

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for DefaultEngine

fn default() -> Self

Returns the “default value” for a type.
