An owned iterator over the set of matches from a regex set.

This will always produces matches in ascending order of index, where the index corresponds to the index of the regex that matched with respect to its position when initially building the set.

This iterator is created by calling SetMatches::into_iter via the IntoIterator trait. This is automatically done in for loops.

Example

use regex::RegexSet;

let set = RegexSet::new([
    r"[0-9]",
    r"[a-z]",
    r"[A-Z]",
    r"\p{Greek}",
]).unwrap();
let hay = "βa1";
let mut matches = vec![];
for index in set.matches(hay) {
    matches.push(index);
}
assert_eq!(matches, vec![0, 1, 3]);
