Struct elasticsearch_dsl::search::aggregations::metrics::CardinalityAggregation

pub struct CardinalityAggregation { /* private fields */ }

A single-value metrics aggregation that calculates an approximate count of distinct values.

Implementations

impl CardinalityAggregation

pub fn precision_threshold(self, precision_threshold: u16) -> Self

The precision_threshold options allows to trade memory for accuracy, and defines a unique count below which counts are expected to be close to accurate. Above this value, counts might become a bit more fuzzy. The maximum supported value is 40000, thresholds above this number will have the same effect as a threshold of 40000. The default value is 3000

pub fn missing<T>(self, missing: T) -> Selfwhere
    T: ToString,

The missing parameter defines how documents that are missing a value should be treated. By default they will be ignored but it is also possible to treat them as if they had a value.

Trait Implementations

impl Clone for CardinalityAggregation

fn clone(&self) -> CardinalityAggregation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CardinalityAggregation

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

Formats the value using the given formatter.

impl From<CardinalityAggregation> for Aggregation

fn from(q: CardinalityAggregation) -> Self

Converts to this type from the input type.

impl PartialEq<CardinalityAggregation> for CardinalityAggregation

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

This method tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for CardinalityAggregation

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

Serialize this value into the given Serde serializer.
