Struct CacheId 

#[repr(transparent)]
pub struct CacheId(pub u8);

A cache whose events we would like to count.

This is used in the Cache type as part of the identification of a cache event. Each variant here corresponds to a particular PERF_COUNT_HW_CACHE_... constant supported by the perf_event_open system call.

Tuple Fields

0: u8

Implementations

impl CacheId

pub const L1D: Self

Level 1 data cache.

pub const L1I: Self

Level 1 instruction cache.

pub const LL: Self

Last-level cache.

pub const DTLB: Self

Data translation lookaside buffer (virtual address translation).

pub const ITLB: Self

Instruction translation lookaside buffer (virtual address translation).

pub const BPU: Self

Branch prediction.

pub const NODE: Self

Memory accesses that stay local to the originating NUMA node.

Trait Implementations

impl Clone for CacheId

fn clone(&self) -> CacheId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheId

where u8: Debug + PartialEq,

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

Formats the value using the given formatter.

impl From<CacheId> for u8

fn from(value: CacheId) -> Self

Converts to this type from the input type.

impl From<u8> for CacheId

fn from(value: u8) -> Self

Converts to this type from the input type.

impl Hash for CacheId

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 CacheId

fn eq(&self, other: &CacheId) -> 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.
