Struct ScalarStats 

pub struct ScalarStats {
    pub mean: f64,
    pub stddev: f64,
    pub ci95_hw: f64,
}

Aggregated statistics across N independent samples of one quantity.

For n < 3 only mean is meaningful; stddev and ci95_hw are reported as 0 and the serializer omits them via skip_serializing_if.

Fields

mean: f64

stddev: f64

ci95_hw: f64

Implementations

impl ScalarStats

pub fn from_samples(xs: &[f64]) -> Self

Aggregate per-run scalars into mean/stddev/CI95 across runs.

xs.len() is the number of repeats. Uses sample variance (divide by n − 1). CI95 half-width via Student’s t (two-sided 95%, df = n − 1).

pub fn differs_from(&self, other: &Self) -> bool

True if the absolute mean difference exceeds the sum of the two half-widths — i.e. the difference is statistically significant at the 95% level (CIs do not overlap).

Trait Implementations

impl Clone for ScalarStats

fn clone(&self) -> ScalarStats

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ScalarStats

impl Debug for ScalarStats

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ScalarStats

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ScalarStats

fn eq(&self, other: &ScalarStats) -> 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 ScalarStats

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
