Struct TokenSet

pub struct TokenSet<D: DistanceMetric> { /* private fields */ }

A TokenSet distance modifies the distance of its inner DistanceMetric to adjust for differences in word orders and word numbers by comparing the intersection of two str with each str.

Implementations

impl<D: DistanceMetric> TokenSet<D>

pub fn new(inner: D) -> Self

Create a new TokenSet distance metric using distance D as base.

Trait Implementations

impl<D: DistanceMetric> DistanceMetric for TokenSet<D>

type Dist = <D as DistanceMetric>::Dist

Represents the data type in which this distance is evaluated.

fn distance<S, T>(&self, a: S, b: T) -> Self::Dist

where S: IntoIterator, T: IntoIterator, <S as IntoIterator>::IntoIter: Clone, <T as IntoIterator>::IntoIter: Clone, <S as IntoIterator>::Item: PartialEq + PartialEq<<T as IntoIterator>::Item>, <T as IntoIterator>::Item: PartialEq,

Generic implementation of the metric.

fn str_distance<S, T>(&self, a: S, b: T) -> Self::Dist

where S: AsRef<str>, T: AsRef<str>,

Evaluates the distance between two str.

fn normalized<S, T>(&self, a: S, b: T) -> f64

where S: IntoIterator, T: IntoIterator, <S as IntoIterator>::IntoIter: Clone, <T as IntoIterator>::IntoIter: Clone, <S as IntoIterator>::Item: PartialEq + PartialEq<<T as IntoIterator>::Item>, <T as IntoIterator>::Item: PartialEq,

Evaluates the normalized distance between two strings A value of ‘0.0’ corresponds to the “zero distance”, both strings are considered equal by means of the metric, whereas a value of ‘1.0’ corresponds to the maximum distance that can exist between the strings.

fn str_normalized<S, T>(&self, a: S, b: T) -> f64

where S: AsRef<str>, T: AsRef<str>,

Convenience normalization for str types.
