Method captures

regex/src/re_bytes.rs:254–261

Returns the capture groups corresponding to the leftmost-first match in `text`. Capture group `0` always corresponds to the entire match. If no match is found, then `None` is returned. You should only use `captures` if you need access to the location of capturing group matches. Otherwise, `find` is faster for discovering the location of the overall match. # Examples Say you have some text with

(&self, text: &'t [u8])

    /// The `0`th capture group is always unnamed, so it must always be
    /// accessed with `get(0)` or `[0]`.
    pub fn captures<'t>(&self, text: &'t [u8]) -> Option<Captures<'t>> {
        let mut locs = self.capture_locations();
        self.captures_read_at(&mut locs, text, 0).map(move |_| Captures {
            text: text,
            locs: locs.0,
            named_groups: self.0.capture_name_idx().clone(),
        })
    }

    /// Returns an iterator over all the non-overlapping capture groups matched
    /// in `text`. This is operationally the same as `find_iter`, except it
