Methods

impl<'t> Captures<'t>

pub fn get(&self, i: usize) -> Option<Match<'t>>

Get the capture group by its index in the regex.

If there is no match for that group or the index does not correspond to a group, None is returned. The index 0 returns the whole match.

Important traits for SubCaptureMatches<'c, 't>

pub fn iter<'c>(&'c self) -> SubCaptureMatches<'c, 't>

Iterate over the captured groups in order in which they appeared in the regex. The first capture corresponds to the whole match.

pub fn len(&self) -> usize
