Struct CpuFeatures 

pub struct CpuFeatures {
    pub sse2: bool,
    pub sse4_2: bool,
    pub popcnt: bool,
    pub avx: bool,
    pub avx2: bool,

}

Detected CPU features for SIMD dispatch

Fields

sse2: bool

SSE2 support

sse4_2: bool

SSE4.2 support

popcnt: bool

POPCNT instruction support

avx: bool

AVX support

avx2: bool

AVX2 support

neon: bool

NEON support (AArch64 only)

Implementations

impl CpuFeatures

pub fn detect() -> Self

Detect CPU features at runtime

This matches the C++ ProcessorSupport::POPCNTenabled() method and extends it to detect all SIMD features used by RustAlign.

pub fn x86_64_v3(&self) -> bool

Check if x86-64-v3 (AVX2) is supported

This matches the C++ __builtin_cpu_supports(“x86-64-v3”) check.

pub fn simd_width(&self) -> usize

Get the best available SIMD width

Trait Implementations

impl Clone for CpuFeatures

fn clone(&self) -> CpuFeatures

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CpuFeatures

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

Formats the value using the given formatter.

impl Default for CpuFeatures

fn default() -> Self

Returns the “default value” for a type.

impl Copy for CpuFeatures
