Implementations

impl Regex

pub fn new(rx: &str) -> Result<Regex, Error>

pub fn new_with_parser(parser: Parser, rx: &str) -> Result<Regex, Error>

pub fn alpha(&self) -> &AlphabetInfo

pub fn initial_state(&mut self) -> StateID

pub fn always_empty(&mut self) -> bool

pub fn is_accepting(&mut self, state: StateID) -> bool

Trait Implementations

impl Clone for Regex

fn clone(&self) -> Regex

impl Debug for Regex

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>
