Extractor enabling patterns that match MatchResult having matches property value of false,
extracting the contained failure message.
For example, you can use this extractor to get the failure message of a MatchResult like this:
matchResult match {
case MatchFailed(failureMessage) => // do something with failureMessage
case _ => // when matchResult.matches equal to true
}
the MatchResult to extract the failure message from.
a Some wrapping the contained failure message if matchResult.matches is equal to true, else None.
