Enum MetricValue 

pub enum MetricValue {
    Double(f64),
    Long(i64),
    Histogram(MetricDistribution),
    Vector(Vec<f64>),
    String(String),
    Boolean(bool),
    Map(HashMap<String, MetricValue>),
}

Represents different types of metric values that analyzers can produce.

This enum covers all common metric types needed for data quality analysis, from simple scalars to complex distributions.

Variants

Double(f64)

A floating-point metric value (e.g., mean, percentage).

Long(i64)

An integer metric value (e.g., count, size).

Histogram(MetricDistribution)

A histogram distribution of values.

Vector(Vec<f64>)

A vector of values (e.g., for multi-dimensional metrics).

String(String)

A string metric value (e.g., mode, most frequent value).

Boolean(bool)

A boolean metric value (e.g., presence/absence).

Map(HashMap<String, MetricValue>)

A map of string keys to metric values (e.g., grouped metrics).

Implementations

impl MetricValue

pub fn is_numeric(&self) -> bool

Checks if the metric value is numeric (Double or Long).

pub fn as_f64(&self) -> Option<f64>

Attempts to get the numeric value as f64.

pub fn as_i64(&self) -> Option<i64>

Attempts to get the value as i64.

pub fn to_string_pretty(&self) -> String

Returns a human-readable string representation of the metric value.

Trait Implementations

impl Clone for MetricValue

fn clone(&self) -> MetricValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MetricValue

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MetricValue

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for MetricValue

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

Formats the value using the given formatter.

impl From<&str> for MetricValue

Implementation for &str values.

fn from(value: &str) -> Self

Converts to this type from the input type.

impl From<String> for MetricValue

Implementation for String values.

fn from(value: String) -> Self

Converts to this type from the input type.

impl From<bool> for MetricValue

Implementation for bool values.

fn from(value: bool) -> Self

Converts to this type from the input type.

impl From<f64> for MetricValue

Implementation for f64 values.

fn from(value: f64) -> Self

Converts to this type from the input type.

impl From<i64> for MetricValue

Implementation for i64 values.

fn from(value: i64) -> Self

Converts to this type from the input type.

impl PartialEq for MetricValue

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl AnalyzerMetric for MetricValue

Blanket implementation for MetricValue itself.
