Struct RegexCacher 

pub struct RegexCacher { /* private fields */ }

Implementations

impl RegexCacher

pub fn new(r: Regex) -> RegexCacher

Wrap a Regex with a fast-path cache that checks if a given known input is already known.

This is faster than whatever caching Regex does internally because of string interning.

pub fn is_match(&self, s: &Rc<String>) -> bool

Does the regex match the string?

pub fn is_match_interned( &self, i: u32, string_cache_inv: &Vec<Rc<String>>, ) -> bool

Does the regex match the string based on its interned ID? See also: Grammar::string_cache_inv
