Struct Sample 

pub struct Sample {
    pub stack: Vec<usize>,
    pub live_objects: usize,
    pub live_bytes: usize,
    pub accum_objects: usize,
    pub accum_bytes: usize,
}

One sampled call stack, copied out of the profiler by samples.

Fields

stack: Vec<usize>

live_objects: usize

live_bytes: usize

accum_objects: usize

accum_bytes: usize

Implementations

impl Sample

pub fn estimated_bytes(&self, sample_rate: usize) -> u64

Estimate the un-sampled byte volume behind this sample.

Mirrors pprof’s legacy heap-sample scaling formula (scaleHeapSample in pprof’s profile/legacy_profile.go), which corrects for the bias a Poisson sampling process with mean interval sample_rate introduces toward larger allocations.

Trait Implementations

impl Clone for Sample

fn clone(&self) -> Sample

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sample

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

Formats the value using the given formatter.
