add hint about starts_for_each_pattern to regex_automata::MatchErrorKind::UnsupportedAnchored documentation #1262
Description
I’ve been there, but the comment is a bit sparse:
An error indicating that a particular type of anchored search was requested, but that the regex engine does not support it.
Just saying that the most common cases/mandatory conditions for DFA/NFA are to have the starts_for_each_pattern might help (I assume that starts_for_each_pattern is mandatory for Anchored(PatternId(_)) variant; I don’t know what’s necessary for the Yes one)
