Enum SimdLevel 

pub enum SimdLevel {
    Scalar = 0,
    Sse42 = 1,
    Avx = 2,
    Avx2 = 3,
    Avx512 = 4,
    Neon = 10,
    Sve = 11,
}

Fine-grained SIMD instruction set level, used by the dispatch layer.

The ordering (Ord derived) is meaningful only within the x86-64 family; ARM levels intentionally have large discriminants so that comparisons across families are not accidentally relied upon.

Variants

Scalar = 0

Scalar (no SIMD).

Sse42 = 1

SSE4.2 (128-bit, x86-64).

Avx = 2

AVX (256-bit, x86-64, no FMA).

Avx2 = 3

AVX2 with FMA (256-bit, x86-64).

Avx512 = 4

AVX-512F+BW+VL (512-bit, x86-64).

Neon = 10

NEON (128-bit, AArch64).

Sve = 11

SVE (scalable, AArch64).

Implementations

impl SimdLevel

pub const fn name(self) -> &'static str

Human-readable name of the level.

pub const fn f64_width(self) -> usize

Number of f64 elements in a vector of this width.

pub const fn f32_width(self) -> usize

Number of f32 elements in a vector of this width.

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.
