Struct CacheOp

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

What sort of cache operation we would like to observe.

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_OP_... constant supported by the perf_event_open system call.

Implementations

impl CacheOp

pub const READ: Self

Read accesses.

pub const WRITE: Self

Write accesses.

pub const PREFETCH: Self

Prefetch accesses.

Trait Implementations

impl Clone for CacheOp

fn clone(&self) -> CacheOp

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CacheOp

where u8: Debug + PartialEq,

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

Formats the value using the given formatter.

impl From<CacheOp> for u8

fn from(value: CacheOp) -> Self

Converts to this type from the input type.

impl From<u8> for CacheOp

fn from(value: u8) -> Self

Converts to this type from the input type.

impl Hash for CacheOp

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 CacheOp

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