Statistics for numeric (integer or float) columns.

Fields

min: f64

max: f64

mean: f64

std_dev: Option<f64>

None when the spread of the values exceeds the finite f64 range. A constant column is Some(0.0), so None never means “no spread”.

variance: Option<f64>

None when the spread of the values exceeds the finite f64 range. A constant column is Some(0.0), so None never means “no spread”.

median: Option<f64>

quartiles: Option<Quartiles>

mode: Option<f64>

coefficient_of_variation: Option<f64>

skewness: Option<f64>

kurtosis: Option<f64>

is_approximate: Option<bool>

outlier_count: Option<usize>

Number of values flagged as IQR-based outliers in this column.

Uses the same Tukey-style detection (Q1 − k·IQR, Q3 + k·IQR with k = 1.5 by default) that feeds the global accuracy.outlier_ratio. None when outlier detection didn’t run (sample below the configured minimum or non-numeric column).

Implementations

impl NumericStats

pub fn empty() -> Self

Trait Implementations

impl Clone for NumericStats

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumericStats

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for NumericStats

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for NumericStats

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

impl Serialize for NumericStats

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
