Struct SimdConfig 

pub struct SimdConfig {
    pub avx512f_enabled: bool,
    pub avx2_enabled: bool,
    pub fma_enabled: bool,
    pub avx512vnni_enabled: bool,
    pub neon_enabled: bool,
    pub dotprod_enabled: bool,
}

Unstable: SIMD dispatch internals; fields may be added as new ISAs are supported.

SIMD configuration with runtime feature detection.

Fields

avx512f_enabled: bool

Unstable: AVX-512F support available (x86_64).

avx2_enabled: bool

Unstable: AVX2 support available (x86_64).

fma_enabled: bool

Unstable: FMA (Fused Multiply-Add) support available (x86_64).

avx512vnni_enabled: bool

Unstable: AVX-512F + AVX-512VNNI support available (x86_64).

neon_enabled: bool

Unstable: NEON support available (aarch64/ARM64).

dotprod_enabled: bool

Unstable: ARM FEAT_DotProd (SDOT/UDOT instructions) available (aarch64).

Mandatory on Armv8.4+; optional on Armv8.2/v8.3. Always false on non-aarch64. SDOT kernels must only be dispatched when this is true.

Implementations

impl SimdConfig

pub fn detect() -> Self

Unstable: feature detection details may change as ISA support expands.

pub fn simd128_enabled(&self) -> bool

Unstable: wasm32 SIMD128 support available.

Unlike the x86_64/aarch64 fields, this is a compile-time, not runtime, signal: wasm has no runtime CPU feature detection (a given .wasm binary either was or wasn’t compiled with -C target-feature=+simd128; there is no dispatching between two codepaths inside one binary). Mirrors cfg!(target_feature = "simd128") and is always false on non-wasm32 targets. A method rather than a field so existing SimdConfig struct literals keep compiling.

pub fn simd_available(&self) -> bool

Unstable: check if any SIMD is available; logic may expand with new ISAs.

Trait Implementations

impl Clone for SimdConfig

fn clone(&self) -> SimdConfig

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

Performs copy-assignment from source.

impl Copy for SimdConfig

impl Debug for SimdConfig

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

Formats the value using the given formatter.

impl Default for SimdConfig

fn default() -> Self

Returns the “default value” for a type.
