Implementations

impl CpuFeatures

pub fn detect() -> Self

Detect features at runtime via cfg and std::thread::available_parallelism.

pub fn best_simd_tier(&self) -> SimdTier

Best SIMD tier available on this CPU.

pub fn recommended_threads(&self) -> usize

Recommended thread count for compute-bound work.

Uses physical cores to avoid contention on hyper-threaded siblings, but guarantees at least 1.

pub fn summary(&self) -> String

One-line human-readable summary.

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 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.
