Struct SampleStats 

pub struct SampleStats {
    pub count: u32,
    pub min: u64,
    pub median: u64,
    pub max: u64,
    pub variance: f64,
    pub std_dev: f64,
    pub cv: f64,
}

Distribution of total_cu across multiple measurement samples.

Only present when a scenario was run more than once on a non-deterministic backend (Scenario::samples > 1); the recorded backend is deterministic, so it never produces this — the tool never fabricates a spread it did not observe.

Fields

count: u32

Number of samples taken.

min: u64

Smallest observed total_cu.

median: u64

Median observed total_cu.

max: u64

Largest observed total_cu.

variance: f64

Population variance of total_cu.

std_dev: f64

Standard deviation of total_cu (sqrt(variance)).

cv: f64

Coefficient of variation (std_dev / mean); 0.0 when the mean is 0.

Implementations

impl SampleStats

pub fn from_samples(totals: &[u64]) -> Option<Self>

Compute statistics over the per-sample total_cu values, or None for fewer than two samples (a single run has no distribution).

Trait Implementations

impl Clone for SampleStats

fn clone(&self) -> SampleStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SampleStats

impl Debug for SampleStats

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for SampleStats

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for SampleStats

fn eq(&self, other: &SampleStats) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for SampleStats

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
