Function combine::regex::captures

pub fn captures<F, R, I>(regex: R) -> Captures<F, R, I> where
    F: FromIterator<I::Range>,
    R: Regex<I::Range>,
    I: FullRangeStream,
    I::Range: Range, 

Matches regex on the input by running captures_iter on the input. Returns the captures of the first match and consumes the input up until the end of that match.
