[−][src]Struct grep_regex::RegexCaptures
Represents the match offsets of each capturing group in a match.
The first, or 0
th capture group, always corresponds to the entire match
and is guaranteed to be present when a match occurs. The next capture
group, at index 1
, corresponds to the first capturing group in the regex,
ordered by the position at which the left opening parenthesis occurs.
Note that not all capturing groups are guaranteed to be present in a match.
For example, in the regex, (?P<foo>\w)|(?P<bar>\W)
, only one of foo
or bar
will ever be set in any given match.
In order to access a capture group by name, you'll need to first find the
index of the group using the corresponding matcher's capture_index
method, and then use that index with RegexCaptures::get
.
