Implementations

impl SimdCapabilities

pub fn detect() -> Self

Detect SIMD capabilities of the current CPU.

pub fn has_instruction_set(&self, isa: SimdInstructionSet) -> bool

Check if a specific instruction set is available.

pub fn has_avx2(&self) -> bool

Check if AVX2 is available.

pub fn has_avx512(&self) -> bool

Check if AVX-512 is available.

pub fn has_neon(&self) -> bool

Check if NEON is available.

pub fn best_instruction_set(&self) -> SimdInstructionSet

Get the best available instruction set.

pub fn recommended_vector_size(&self, element_size: usize) -> usize

Get the recommended vectorization factor for a given element size.

Trait Implementations

impl Clone for SimdCapabilities

fn clone(&self) -> SimdCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimdCapabilities

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

Formats the value using the given formatter.

impl Default for SimdCapabilities

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SimdCapabilities

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SimdCapabilities

fn eq(&self, other: &SimdCapabilities) -> 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 Serialize for SimdCapabilities

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
