Struct DefaultEngine

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

Engine that at runtime selects the best Engine.

Implementations

impl DefaultEngine

pub fn new() -> Self

Creates new DefaultEngine by chosing and initializing the underlying engine.

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

1. Avx2
2. Ssse3
3. NoSimd

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

1. [Neon]
2. NoSimd
