Enum SimdLevel 

pub enum SimdLevel {
    Scalar,
    Sse2,
    Avx,
    Avx2,
    Avx512,
    Neon,
}

CPU feature detection for runtime SIMD dispatch. Available SIMD instruction sets.

Variants

Scalar

No SIMD, use scalar code.

Sse2

SSE2 (128-bit, available on all x86-64).

Avx

AVX (256-bit float).

Avx2

AVX2 (256-bit integer + FMA).

Avx512

AVX-512 (512-bit).

Neon

ARM NEON (128-bit).

Implementations

impl SimdLevel

pub fn detect() -> Self

Detect the best available SIMD level at runtime.

pub fn width_bytes(&self) -> usize

Get the SIMD width in bytes.

pub fn f32_width(&self) -> usize

Get the number of f32 elements that fit in one SIMD register.

pub fn f64_width(&self) -> usize

Get the number of f64 elements that fit in one SIMD register.

Trait Implementations

impl Clone for SimdLevel

fn clone(&self) -> SimdLevel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimdLevel

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

Formats the value using the given formatter.

impl Ord for SimdLevel

fn cmp(&self, other: &SimdLevel) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for SimdLevel

fn eq(&self, other: &SimdLevel) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for SimdLevel

fn partial_cmp(&self, other: &SimdLevel) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
