Struct Morpheme

pub struct Morpheme<'a, T> { /* private fields */ }

A morpheme (basic semantic unit of language)

Implementations

impl<T: DictionaryAccess> Morpheme<'_, T>

pub fn part_of_speech(&self) -> &[String]

Returns the part of speech

impl<T: DictionaryAccess + Clone> Morpheme<'_, T>

pub fn split(&self, mode: Mode) -> SudachiResult<MorphemeList<T>>

👎Deprecated since 0.6.1: use split_into

Returns new morpheme list splitting the morpheme with given mode.

impl<'a, T: DictionaryAccess> Morpheme<'a, T>

pub fn begin(&self) -> usize

Returns the begin index in bytes of the morpheme in the original text

pub fn end(&self) -> usize

Returns the end index in bytes of the morpheme in the original text

pub fn begin_c(&self) -> usize

Returns the codepoint offset of the morpheme begin in the original text

pub fn end_c(&self) -> usize

Returns the codepoint offset of the morpheme begin in the original text

pub fn surface(&self) -> Ref<'_, str>

Returns a substring of the original text which corresponds to the morpheme

pub fn part_of_speech_id(&self) -> u16

pub fn dictionary_form(&self) -> &str

Returns the dictionary form of morpheme

“Dictionary form” means a word’s lemma and “終止形” in Japanese.

pub fn normalized_form(&self) -> &str

Returns the normalized form of morpheme

This method returns the form normalizing inconsistent spellings and inflected forms

pub fn reading_form(&self) -> &str

Returns the reading form of morpheme.

Returns Japanese syllabaries ‘フリガナ’ in katakana.

pub fn is_oov(&self) -> bool

Returns if this morpheme is out of vocabulary

pub fn word_id(&self) -> WordId

Returns the word id of morpheme

pub fn dictionary_id(&self) -> i32

Returns the dictionary id where the morpheme belongs

Returns -1 if the morpheme is oov

pub fn synonym_group_ids(&self) -> &[u32]

pub fn get_word_info(&self) -> &WordInfo

pub fn index(&self) -> usize

Returns the index of this morpheme

pub fn split_into( &self, mode: Mode, out: &mut MorphemeList<T>, ) -> SudachiResult<bool>

Splits morpheme and writes sub-morphemes into the provided list. The resulting list is not cleared before that. Returns true if split has produced any elements.

pub fn total_cost(&self) -> i32

Returns total cost from the beginning of the path
