Struct regex_automata::util::captures::GroupInfoError

pub struct GroupInfoError { /* private fields */ }

An error that may occur when building a GroupInfo.

Building a GroupInfo does a variety of checks to make sure the capturing groups satisfy a number of invariants. This includes, but is not limited to, ensuring that the first capturing group is unnamed and that there are no duplicate capture groups for a specific pattern.
