Enum CpuFeature

pub enum CpuFeature {
    SSE2,
    SSE3,
    SSSE3,
    SSE41,
    SSE42,
    POPCNT,
    AVX,
    BMI1,
    BMI2,
    AVX2,
    AVX512DQ,
    AVX512VL,
    AVX512F,
    LZCNT,
    NEON,
}

The nomenclature is inspired by the cpuid crate. The list of supported features was initially retrieved from cranelift-native.

The CpuFeature enum values are likely to grow closer to the original cpuid. However, we prefer to start small and grow from there.

If you would like to use a flag that doesn’t exist yet here, please open a PR.

const CONST_HELPER_INSTANCE: __EnumSetConstHelper = __EnumSetConstHelper

The instance of the ConstHelper.

const ALL_BITS: Self::Repr = {transmute(0x7fff): <compilation::target::CpuFeature as enumset::__internal::EnumSetTypePrivate>::Repr}

A mask of bits that are valid in the bitset.

const BIT_WIDTH: u32 = 15u32

The largest bit used in the bitset.

const VARIANT_COUNT: u32 = 15u32

The number of variants in the bitset.

fn enum_into_u32(self) -> u32

Converts an enum of this type into its bit position.

unsafe fn enum_from_u32(val: u32) -> Self

Converts a bit position into an enum value.

impl FromStr for CpuFeature

type Err = ParseCpuFeatureError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for CpuFeature

fn hash<__H: Hasher>(&self, state: &mut __H)

impl PartialEq<EnumSet<CpuFeature>> for CpuFeature

fn eq(&self, other: &EnumSet<CpuFeature>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
