Struct Regex 

pub struct Regex { /* private fields */ }

compiled regex backed by a lazy DFA.

uses a Mutex for mutable DFA state; clone for per-thread matching.

Implementations

impl Regex

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

compile with default options.

pub fn with_options(pattern: &str, opts: EngineOptions) -> Result<Regex, Error>

compile with custom options.

pub fn from_node( b: RegexBuilder, node: NodeId, opts: EngineOptions, ) -> Result<Regex, Error>

build from a pre-constructed AST node.

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

(fwd_states, rev_states) count.

pub fn find_all(&self, input: &[u8]) -> Result<Vec<Match>, Error>

all non-overlapping matches, left-to-right.

pub fn effects_debug(&self) -> String

debug: dump rev DFA effects_id and effects.

pub fn collect_rev_nulls_debug(&self, input: &[u8]) -> Vec<usize>

debug: run only the reverse DFA, return null positions.

pub fn find_anchored(&self, input: &[u8]) -> Result<Option<Match>, Error>

longest match anchored at position 0, forward DFA only.

pub fn is_match(&self, input: &[u8]) -> Result<bool, Error>

whether the pattern matches anywhere in the input.
