pub fn re_captures<'a, E>(
re: Regex,
) -> impl Fn(&'a str) -> IResult<&'a str, Vec<Vec<&'a str>>, E>where
E: ParseError<&'a str>,
Expand description
Compares the input with a regular expression and returns
the capture groups of all matches in a nested Vec
.
Requires the regexp
feature.
ยงExample
let re = regex::Regex::new(r"(a)(\d)").unwrap();
let parser = re_captures::<(&str, ErrorKind)>(re);
assert_eq!(parser("a1ba2"), Ok(("", vec![vec!["a1", "a", "1"], vec!["a2", "a", "2"]])));
assert_eq!(parser("abc"), Err(Err::Error(("abc", ErrorKind::RegexpCapture))));
