Struct RegexQueryProcessor 

pub struct RegexQueryProcessor { /* private fields */ }

Query processor implementation based on regular expressions

Examples

let regex_query_processor = RegexQueryProcessor::create(r#"a+"#).unwrap();
let parts = regex_query_processor.matching("bbabbbaab").unwrap();
assert_eq!(
  parts,
  Match::parts(vec![
    Part::non_matching("bb"),
    Part::matching("a"),
    Part::non_matching("bbb"),
    Part::matching("aa"),
    Part::non_matching("b"),
  ])
);
