MatchResult
havingmatches
property value offalse
, 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
}- matchResult
the
MatchResult
to extract the failure message from.- returns
a
