Enum PerfMode

pub enum PerfMode {
    Instructions,
    Cycles,
    Branches,
    BranchMisses,
    CacheRefs,
    CacheMisses,
    BusCycles,
    RefCycles,
}

The perf counter to measure when running a benchmark.

Variants

Instructions

The number of instructions retired. These can be affected by various issues, most notably hardware interrupt counts.

Cycles

The total number of CPU cycles. This can be affected by CPU frequency scaling.

Branches

The number of branch instructions retired.

BranchMisses

The number of mispredicted branches.

CacheRefs

The number of cache accesses.

CacheMisses

The number of cache misses.

BusCycles

The number of bus cycles elapsed.

RefCycles

The total number of CPU cycles elapsed. This is not affected by CPU frequency scaling.

Trait Implementations

impl Clone for PerfMode

fn clone(&self) -> PerfMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PerfMode

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

Formats the value using the given formatter.

impl PartialEq for PerfMode

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