source

pub fn get_left_cardinality(&self) -> F

Returns the estimated cardinality of the left set.

Examples

use hyperloglog_rs::EstimatedUnionCardinalities;

let estimated_union_cardinalities = EstimatedUnionCardinalities::from((2.0, 3.0, 4.0));

let left_cardinality = estimated_union_cardinalities.get_left_cardinality();

assert_eq!(left_cardinality, 2.0);

source

pub fn get_right_cardinality(&self) -> F

Returns the estimated cardinality of the right set.

Examples

use hyperloglog_rs::EstimatedUnionCardinalities;

let estimated_union_cardinalities = EstimatedUnionCardinalities::from((2.0, 3.0, 4.0));

let right_cardinality = estimated_union_cardinalities.get_right_cardinality();

assert_eq!(right_cardinality, 3.0);

source

pub fn get_union_cardinality(&self) -> F

Returns the estimated cardinality of the union of the two sets.

Examples

use hyperloglog_rs::EstimatedUnionCardinalities;

let estimated_union_cardinalities = EstimatedUnionCardinalities::from((2.0, 3.0, 4.0));

let union_cardinality = estimated_union_cardinalities.get_union_cardinality();

assert_eq!(union_cardinality, 4.0);

source

pub fn get_intersection_cardinality(&self) -> F

Returns the estimated cardinality of the intersection of the two sets.

Examples

use hyperloglog_rs::EstimatedUnionCardinalities;

let estimated_union_cardinalities = EstimatedUnionCardinalities::from((2.0, 3.0, 4.0));

let intersection_cardinality = estimated_union_cardinalities.get_intersection_cardinality();

assert_eq!(intersection_cardinality, 1.0);

source

pub fn get_left_difference_cardinality(&self) -> F

Returns the estimated cardinality of the left set minus the right set.

Examples

use hyperloglog_rs::EstimatedUnionCardinalities;

let estimated_union_cardinalities = EstimatedUnionCardinalities::from((2.0, 3.0, 4.0));

let left_minus_right_cardinality = estimated_union_cardinalities.get_left_difference_cardinality();

assert_eq!(left_minus_right_cardinality, 1.0);

source

pub fn get_right_difference_cardinality(&self) -> F

Returns the estimated cardinality of the right set minus the left set.

Examples

use hyperloglog_rs::EstimatedUnionCardinalities;

let estimated_union_cardinalities = EstimatedUnionCardinalities::from((2.0, 3.0, 4.0));

let right_minus_left_cardinality = estimated_union_cardinalities.get_right_difference_cardinality();

assert_eq!(right_minus_left_cardinality, 2.0);

source

pub fn get_symmetric_difference_cardinality(&self) -> F

Returns the estimated cardinality of the symmetric difference of the two sets.

Examples

use hyperloglog_rs::EstimatedUnionCardinalities;

let estimated_union_cardinalities = EstimatedUnionCardinalities::from((2.0, 3.0, 4.0));

let symmetric_difference_cardinality = estimated_union_cardinalities.get_symmetric_difference_cardinality();

assert_eq!(symmetric_difference_cardinality, 3.0);

source

pub fn get_jaccard_index(&self) -> F

Returns the estimated Jaccard index of the two sets.

Examples

use hyperloglog_rs::EstimatedUnionCardinalities;

let estimated_union_cardinalities = EstimatedUnionCardinalities::from((2.0, 3.0, 4.0));

let jaccard_index = estimated_union_cardinalities.get_jaccard_index();

assert_eq!(jaccard_index, 1.0 / 4.0, "Example 1: Expected 1.0 / 4.0, got {}", jaccard_index);
