Struct hyperminhash::Sketch

pub struct Sketch { /* private fields */ }

Records the approximate number of unique elements it has seen over it’s lifetime.

Implementations

impl Sketch

pub fn add(&mut self, v: impl Hash)

Add an element to this set, using the element’s Hash-implementation

pub fn add_bytes(&mut self, v: &[u8])

Add a single element given by raw bytes to this set

pub fn cardinality(&self) -> f64

The approximate number of unique elements in the set.

pub fn union<'a>(&'a mut self, other: &Self) -> &'a Self

Merge two sets, resulting in this set becoming the union-set.

pub fn similarity(&self, other: &Self) -> f64

The Jaccard Index similarity estimation

pub fn intersection(&self, other: &Self) -> f64

The approximate number of elements in both sets

Trait Implementations

impl Clone for Sketch

fn clone(&self) -> Sketch

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Sketch

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

Formats the value using the given formatter.

impl Default for Sketch

fn default() -> Self

Returns the “default value” for a type.

impl<T: Hash> FromIterator<T> for Sketch

fn from_iter<I: IntoIterator<Item = T>>(iter: I) -> Self

Creates a value from an iterator.

impl Hash for Sketch

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Sketch

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

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

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.
