Struct MeasureRegion 

pub struct MeasureRegion { /* private fields */ }

Measure code block performance by collecting samples. It relies on the fact that objects get destroyed at the end of the block.

let mut loop_timing = MeasureRegion::new();
for _ in 0..N {
  let _ = loop_timing.get_sample();
  foo();
}
let cpu_cycles = loop_timing.get_average_sample() *
  CPUInfo::get_frequency_hz().tsc_scaling;

Implementations

impl MeasureRegion

pub fn new_named(region_name: String, dump_on_drop: bool) -> Self

pub fn new() -> Self

pub fn get_sample(&mut self) -> MeasureSample<'_>

pub fn get_average_sample(&self) -> f32

pub fn get_total_time(&self) -> u64

Get total running time in milliseconds

Trait Implementations

impl Drop for MeasureRegion

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
