Struct pmu_x86::stat::PerformanceCounters

pub struct PerformanceCounters { /* private fields */ }

Implementations

impl PerformanceCounters

pub fn new() -> Result<PerformanceCounters, &'static str>

Initialize seven performance monitoring counters. They will measure:

• Instructions retired
• Core cycles
• Reference cycles
• LLC references
• LLC misses
• Branch instructions retired
• Branch misses retired

pub fn start(&mut self) -> Result<(), &'static str>

Start running all the counters

pub fn end(self) -> Result<PMUResults, &'static str>

Stop the counters and return the counter values. The PerformanceCounters object is consumed since the counters are freed in this function and should not be accessed again.
