Struct Language 

pub struct Language { /* private fields */ }

A pattern compiled to a term and a lazily built automaton.

Implementations

impl Language

pub fn compile( p: &Pattern, alphabet: Option<Alphabet>, mode: Mode, limits: &Limits, ) -> Result<Language, RexactError>

Compile a parsed pattern. alphabet defaults per dialect.

pub fn from_parts( store: TermStore, root: TermId, alphabet: Alphabet, limits: &Limits, ) -> Result<Language, RexactError>

Wrap an existing term (used by the analyses and by tests).

pub fn alphabet(&self) -> Alphabet

The alphabet mode, reported with every result.

pub fn root(&self) -> TermId

The root term.

pub fn store(&self) -> &TermStore

The term store (read-only).

pub fn matches(&mut self, input: &str) -> Result<bool, RexactError>

Full-match test on text, encoded per the alphabet mode.

pub fn matches_units(&mut self, input: &[u32]) -> Result<bool, RexactError>

Full-match test on symbols.

pub fn minimal(&mut self) -> Result<MinDfa, RexactError>

Minimal complete automaton in canonical form.

pub fn fingerprint(&mut self) -> Result<String, RexactError>

Language fingerprint: equal for equal languages in the same alphabet.

pub fn stats(&self) -> (usize, usize)

(states built so far, symbol classes).
