Expand description

Atomic counters for recording statistics on calls of a single function.

Fields§

§num_calls: AtomicU64

Number of function calls.

§total_time_ns: AtomicU64

Total time spent in this function.

§min_time_ns: AtomicU64

Shortest measured duration spend in this function.

§max_time_ns: AtomicU64

Longest measured duration spend in this function.

Implementations§

source§

impl PerfCounter

source

pub fn atomic_read(&self) -> PerfCounterResult

Atomically read the current state of the counter.

source§

impl PerfCounter

source

fn start_measurement(&self) -> PerfCounterManager<'_>

Start measuring the spent time. Must call stop() on the return value.

source

fn measure<R>(&self, f: impl FnOnce() -> R) -> R

Measure the execution time of f and add it to the statistics.
