Struct CpuFeatures

pub struct CpuFeatures(/* private fields */);

Available on crate feature compiler only.

CPU feature support flags

Implementations

impl CpuFeatures

pub const NONE: Self

Disable all cpu feature support flags.

pub const AVX2: Self

Intel(R) Advanced Vector Extensions 2 (Intel(R) AVX2)

Setting this flag indicates that the target platform supports AVX2 instructions.

pub const AVX512: Self

Intel(R) Advanced Vector Extensions 512 (Intel(R) AVX512)

Setting this flag indicates that the target platform supports AVX512 instructions, specifically AVX-512BW. Using AVX512 implies the use of AVX2.

pub const AVX512VBMI: Self

Intel(R) Advanced Vector Extensions 512 Vector Byte Manipulation Instructions (Intel(R) AVX512VBMI)

Setting this flag indicates that the target platform supports AVX512VBMI instructions. Using AVX512VBMI implies the use of AVX512.

impl BitSet for CpuFeatures

fn nonzero(&self) -> bool

Whether the underlying integer storing this bitset is not equal to 0.

fn contains(&self, other: &Self) -> bool

Whether the other flag was provided to the current bitset.

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 Default for CpuFeatures

fn default() -> CpuFeatures

Returns the “default value” for a type.

impl Hash for CpuFeatures

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

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 CpuFeatures

type Output = CpuFeatures

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl Ord for CpuFeatures

fn cmp(&self, other: &CpuFeatures) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for CpuFeatures

fn partial_cmp(&self, other: &CpuFeatures) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
