Struct CpuFeatures

pub struct CpuFeatures {
    pub sse42: bool,
    pub avx2_fma: bool,
    pub avx512: bool,
    pub neon: bool,
}

Runtime-detected CPU capabilities. No compile-time target-cpu=native is required, so one binary remains safe on older machines.

Fields

sse42: bool

SSE4.2 available.

avx2_fma: bool

AVX2 and FMA available.

avx512: bool

AVX-512 foundation and DQ available.

neon: bool

AArch64 NEON available.

Implementations

impl CpuFeatures

pub fn detect() -> CpuFeatures

Detect features on the current process host.

pub const fn supports(self, instruction_set: CpuInstructionSet) -> bool

Whether one implementation is safe to execute.

pub const fn best(self) -> CpuInstructionSet

Best compiled-compatible specialization, or portable scalar.

Trait Implementations

impl Clone for CpuFeatures

fn clone(&self) -> CpuFeatures

Returns a copy 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<(), Error>

Formats the value using the given formatter.

impl PartialEq for CpuFeatures

fn eq(&self, other: &CpuFeatures) -> 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.
