Struct libreda_db::profile::PerfCounter

pub struct PerfCounter {
    num_calls: AtomicU64,
    total_time_ns: AtomicU64,
    min_time_ns: AtomicU64,
    max_time_ns: AtomicU64,
}

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

impl PerfCounter

pub fn atomic_read(&self) -> PerfCounterResult

Atomically read the current state of the counter.

impl PerfCounter

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

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

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

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

Trait Implementations

impl Debug for PerfCounter

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

Formats the value using the given formatter.

impl Default for PerfCounter

fn default() -> Self

Returns the “default value” for a type.
