Detailed Description

QDebug operator<<(QDebug dbg, const Message &message)
QDebugStateSaver saver(dbg);
QList<QStringView> pieces = message.body().split("\r\n", QStringParser::SkipEmptyParts);
if (pieces.isEmpty()) {
dbg.nospace() << "Message()";
} else if (pieces.size() == 1) {
dbg.nospace() << "Message(" << pieces.first() << ")";
} else {
dbg.nospace() << "Message(" << pieces.first() << " ...)";
return dbg;
