Forbid implicit conversions between QFuture and other types
- Remove the casting operator of QFuture<T> to T. It calls
QFuture::result(), which may lead to undefined behavior if the user
has moved the results from QFuture via QFuture::takeResult() before
trying to do the conversion.
- Disable implicit conversion of QFuture<T> to QFuture<void>, by making
the constructor explicit. If the users really intend to do the
conversion, they should do it explicitly.
[ChangeLog][Source-Incompatible Changes][QFuture] Implicit conversions
of QFuture<T> to T and to QFuture<void> have been disabled. Use
QFuture::result() or QFuture::takeResult() where you need to convert
QFuture<T> to T. Use the explicit QFuture<void>(const QFuture<T> &)
constructor to convert QFuture<T> to QFuture<void>.
