Struct FeatureSet

pub struct FeatureSet(pub [u64; 4]);

The set of features used in the perf file. The perf file contains one feature section for each feature.

This set is provided in the perf file header. It has room for 4 * 64 = 256 feature bits.

Tuple Fields

0: [u64; 4]

Implementations

impl FeatureSet

pub const MAX_BITS: u32 = 256u32

pub fn len(&self) -> usize

The number of features in this set.

pub fn is_empty(&self) -> bool

Whether the set is empty.

pub fn iter(&self) -> FeatureSetIter

Returns an iterator over all features in this set, from low to high.

pub fn has_feature(&self, feature: Feature) -> bool

Checks if the feature is contained in this set.

Trait Implementations

impl Clone for FeatureSet

fn clone(&self) -> FeatureSet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FeatureSet

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

Formats the value using the given formatter.

impl Hash for FeatureSet

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 PartialEq for FeatureSet

fn eq(&self, other: &FeatureSet) -> bool

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

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

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