QAnyStringView qToAnyStringViewIgnoringNull ( const QStringLike & s )

inlinenodiscardnoexcept

Since

6.0

Convert s to a QAnyStringView ignoring {s.isNull()}.

Returns a string view that references {s}'s data, but is never null.

This is a faster way to convert a QString or QByteArray to a QAnyStringView, if null QStrings or QByteArrays can legitimately be treated as empty ones.
