Struct Hardware 

#[repr(transparent)]
pub struct Hardware(pub u64);

Hardware counters.

These are counters implemented by the processor itself. Such counters vary from one architecture to the next, and even different models within a particular architecture will often change the way they expose this data. This is a selection of portable names for values that can be obtained on a wide variety of systems.

Each variant of this enum corresponds to a particular PERF_COUNT_HW_… value supported by the perf_event_open system call.

Trait Implementations

impl Clone for Hardware

fn clone(&self) -> Hardware

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hardware

where u64: Debug + PartialEq,

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

Formats the value using the given formatter.

impl Event for Hardware

fn update_attrs(self, attr: &mut perf_event_attr)

Update the perf_event_attr struct so that it will record the requested event.

fn update_attrs_with_data( self, attr: &mut perf_event_attr, ) -> Option<Arc<dyn EventData>>

Update the perf_event_attr struct so that it will record the requested event.

impl From<Hardware> for u64

fn from(value: Hardware) -> Self

Converts to this type from the input type.

impl From<u64> for Hardware

fn from(value: u64) -> Self

Converts to this type from the input type.

impl Hash for Hardware

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 Hardware

fn eq(&self, other: &Hardware) -> 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 Copy for Hardware

impl Eq for Hardware

impl StructuralPartialEq for Hardware
