Struct SynonymRegistry 

pub struct SynonymRegistry { /* private fields */ }

Registry of synonym groups. Each group is an ordered list; ties in recency are broken by registration order (first-registered wins).

An inverted index (index) maps each lowercased word to its group so that synonyms_for is O(1) rather than O(groups × group_size).

Implementations

impl SynonymRegistry

pub fn new() -> Self

pub fn register_group(&mut self, words: &[&str])

Register a new synonym group. Order of insertion is preserved and used to break ties when multiple synonyms have equal recency.

pub fn synonyms_for(&self, word: &str) -> Option<&[String]>

Look up the synonym group a word belongs to.

Matching is case-insensitive. Returns None when the word is not registered in any group.

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize
