Struct LevenshteinMetric2 

pub struct LevenshteinMetric2 {
    pub max_dist: Option<usize>,
}

Levenshtein metric (version 2) with additional operations.

Fields

max_dist: Option<usize>

Maximum allowed distance (None = unlimited).

Implementations

impl LevenshteinMetric2

pub fn new() -> Self

Create an unbounded metric.

pub fn with_max(d: usize) -> Self

Create with a maximum distance threshold.

pub fn distance(&self, a: &str, b: &str) -> usize

Compute the distance between two strings.

pub fn within_threshold(&self, a: &str, b: &str) -> bool

Check if distance is within threshold.

pub fn identity_law(&self, a: &str) -> bool

Check metric identity: d(a, a) = 0.

pub fn symmetry_law(&self, a: &str, b: &str) -> bool

Check metric symmetry: d(a, b) = d(b, a).

Trait Implementations

impl Default for LevenshteinMetric2

fn default() -> Self

Returns the “default value” for a type.
