Enum WhichCache 

#[repr(u32)]
pub enum WhichCache {
    L1D = 0,
    L1I = 1,
    LL = 2,
    DTLB = 3,
    ITLB = 4,
    BPU = 5,
    NODE = 6,
}

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.

Variants

L1D = 0

for measuring Level 1 Data Cache

L1I = 1

for measuring Level 1 Instruction Cache

LL = 2

for measuring Last-Level Cache

DTLB = 3

for measuring the Data TLB

ITLB = 4

for measuring the Instruction TLB

BPU = 5

for measuring the branch prediction unit

NODE = 6

(since Linux 3.1) for measuring local memory accesses

Trait Implementations

impl Clone for WhichCache

fn clone(&self) -> WhichCache

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WhichCache

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

Formats the value using the given formatter.

impl PartialEq for WhichCache

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