Struct Hamming 

pub struct Hamming {
    pub ignore_case: bool,
}

Hamming distance as a StringMetric.

Incomparable inputs measure as -1.0, matching the scalar API.

Fields

ignore_case: bool

Fold case before comparing.

Trait Implementations

impl Clone for Hamming

fn clone(&self) -> Hamming

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Hamming

impl Debug for Hamming

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

Formats the value using the given formatter.

impl Default for Hamming

fn default() -> Hamming

Returns the “default value” for a type.

impl StringMetric for Hamming

const IS_SIMILARITY: bool = false

true when a larger value means “more similar” (e.g. Jaro–Winkler, Dice), false when a larger value means “further apart” (e.g. Levenshtein, Hamming).

fn measure(&self, a: &str, b: &str) -> f64

Computes the metric between two strings.
