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.

Trait Implementations

impl<O> BitAnd<O> for CpuFeature

where O: Into<EnumSet<CpuFeature>>,

type Output = EnumSet<CpuFeature>

The resulting type after applying the & operator.

fn bitand(self, other: O) -> <CpuFeature as BitAnd<O>>::Output

Performs the & operation.

impl<O> BitOr<O> for CpuFeature

where O: Into<EnumSet<CpuFeature>>,

type Output = EnumSet<CpuFeature>

The resulting type after applying the | operator.

fn bitor(self, other: O) -> <CpuFeature as BitOr<O>>::Output

Performs the | operation.

impl<O> BitXor<O> for CpuFeature

where O: Into<EnumSet<CpuFeature>>,

type Output = EnumSet<CpuFeature>

The resulting type after applying the ^ operator.

fn bitxor(self, other: O) -> <CpuFeature as BitXor<O>>::Output

Performs the ^ operation.

impl Clone for CpuFeature

fn clone(&self) -> CpuFeature

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CpuFeature

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

Formats the value using the given formatter.

impl Display for CpuFeature

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

Formats the value using the given formatter.

impl FromStr for CpuFeature

type Err = ParseCpuFeatureError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<CpuFeature, <CpuFeature as FromStr>::Err>

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

impl Hash for CpuFeature

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

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Not for CpuFeature

type Output = EnumSet<CpuFeature>

The resulting type after applying the ! operator.

fn not(self) -> <CpuFeature as Not>::Output

Performs the unary ! operation.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
