Struct LexiconIndex 

pub struct LexiconIndex { /* private fields */ }

Index for querying the lexicon by features, sorts, and classes.

Implementations

impl LexiconIndex

pub fn new() -> LexiconIndex

Load and parse the lexicon from the embedded JSON file.

pub fn proper_nouns(&self) -> Vec<&NounEntry>

Get all nouns marked with the “Proper” feature (names).

pub fn common_nouns(&self) -> Vec<&NounEntry>

Get all nouns NOT marked as proper (common nouns).

pub fn nouns_with_feature(&self, feature: &str) -> Vec<&NounEntry>

Get all nouns with a specific feature (case-insensitive).

pub fn nouns_with_sort(&self, sort: &str) -> Vec<&NounEntry>

Get all nouns with a specific semantic sort (case-insensitive).

pub fn verbs_with_feature(&self, feature: &str) -> Vec<&VerbEntry>

Get all verbs with a specific feature (case-insensitive).

pub fn verbs_with_class(&self, class: &str) -> Vec<&VerbEntry>

Get all verbs with a specific Vendler class (case-insensitive).

pub fn intransitive_verbs(&self) -> Vec<&VerbEntry>

Get all verbs that are intransitive (no Transitive/Ditransitive feature).

pub fn transitive_verbs(&self) -> Vec<&VerbEntry>

Returns all verbs that take a direct object.

Includes both transitive verbs (two-place predicates) and ditransitive verbs (three-place predicates). Verbs are matched if they have either the "Transitive" or "Ditransitive" feature (case-insensitive).

pub fn adjectives_with_feature(&self, feature: &str) -> Vec<&AdjectiveEntry>

Returns all adjectives with a specific feature (case-insensitive).

Common features include "Intersective", "Subsective", "NonIntersective", and "Gradable". See crate::Feature for the full list.

pub fn intersective_adjectives(&self) -> Vec<&AdjectiveEntry>

Returns all adjectives with intersective semantics.

Intersective adjectives combine with nouns via set intersection: “red ball” denotes things that are both red and balls. This is a convenience method equivalent to adjectives_with_feature("Intersective").

pub fn random_proper_noun(&self, rng: &mut impl Rng) -> Option<&NounEntry>

Selects a random proper noun from the lexicon.

Returns None if the lexicon contains no proper nouns.

pub fn random_common_noun(&self, rng: &mut impl Rng) -> Option<&NounEntry>

Selects a random common noun from the lexicon.

Returns None if the lexicon contains no common nouns.

pub fn random_verb(&self, rng: &mut impl Rng) -> Option<&VerbEntry>

Selects a random verb from the lexicon.

Returns None if the lexicon contains no verbs.

pub fn random_intransitive_verb(&self, rng: &mut impl Rng) -> Option<&VerbEntry>

Selects a random intransitive verb from the lexicon.

Returns None if the lexicon contains no intransitive verbs.

pub fn random_transitive_verb(&self, rng: &mut impl Rng) -> Option<&VerbEntry>

Selects a random transitive or ditransitive verb from the lexicon.

Returns None if the lexicon contains no transitive verbs.

pub fn random_adjective(&self, rng: &mut impl Rng) -> Option<&AdjectiveEntry>

Selects a random adjective from the lexicon.

Returns None if the lexicon contains no adjectives.

pub fn random_intersective_adjective( &self, rng: &mut impl Rng, ) -> Option<&AdjectiveEntry>

Selects a random intersective adjective from the lexicon.

Returns None if the lexicon contains no intersective adjectives.

Trait Implementations

impl Default for LexiconIndex

Creates a LexiconIndex by loading and parsing the embedded lexicon JSON.

Equivalent to calling LexiconIndex::new().

fn default() -> LexiconIndex

Returns the “default value” for a type.
