[noexcept]
QByteArray operator""_qba(const char *str, size_t size)
\since
6.2 \deprecated
[6.8] Use _ba
from Qt::StringLiterals namespace instead.
Literal operator that creates a QByteArray out of the first size characters in the char string literal str.
The QByteArray is created at compile time, and the generated string data is stored in the read-only segment of the compiled object file. Duplicate literals may share the same read-only memory. This functionality is interchangeable with QByteArrayLiteral, but saves typing when many string literals are present in the code.
The following code creates a QByteArray:
auto str = "hello"_qba;

[noexcept]
QString operator""_qs(const char16_t *str, size_t size)
\since
6.2 \deprecated
[6.8] Use _s
from Qt::StringLiterals namespace instead.
Literal operator that creates a QString out of the first size characters in the char16_t string literal str.
The QString is created at compile time, and the generated string data is stored in the read-only segment of the compiled object file. Duplicate literals may share the same read-only memory. This functionality is interchangeable with QStringLiteral, but saves typing when many string literals are present in the code.
The following code creates a QString:
auto str = u"hello"_qs;
