namespace Qt::Literals

The Qt::Literals inline namespace holds the user-defined literal operators of Nt, so they are found through using namespace Qt::Literals, using namespace Qt::StringLiterals or using namespace Qt. The string literals _s (a QString from a u"" literal) and _L1 (a QLatin1StringView or QChar from a Latin-1 literal) are provided.
