Struct Normalizer 

pub struct Normalizer { /* private fields */ }

A configured CJK normalization pipeline.

Create via Normalizer::builder() for ergonomic defaults, or supply a NormalizerConfig directly via Normalizer::with_config.

Implementations

impl Normalizer

pub fn builder() -> NormalizerBuilder

Returns a builder with Japanese-oriented defaults: strip_ivs: true, fold_variants: true, width_normalization: true.

Note: these defaults differ from NormalizerConfig::default(), which keeps width_normalization: false for backward compatibility with the standalone normalize() function.

pub fn with_config(config: NormalizerConfig) -> Self

Create a Normalizer from an explicit NormalizerConfig.

pub fn normalize<'a>(&self, input: &'a str) -> Result<Cow<'a, str>>

Normalize input according to this normalizer’s configuration.

Returns Cow::Borrowed when no substitutions are made (zero allocation).

pub fn matches(&self, a: &str, b: &str) -> Result<bool>

Return true if a and b are equivalent under this normalizer’s configuration.

pub fn similarity(&self, a: &str, b: &str) -> Result<f32>

Compute a Jaro-Winkler similarity score between a and b using this normalizer’s full pipeline (including width normalization) before comparison.

Returns a value in [0.0, 1.0] where 1.0 means identical after normalization.
