QThreadPool::start() overload taking move-only functions

    • c080d1e64 (dev), 0e7e1c339 (dev)

      QThreadPool::start() has an overload that takes a std::function. However, since std::function must be copyable, it's not possible to pass move-only lambdas. For example

      FileDescriptor fd{42};
// FileDescriptor is move only

QThreadPool::globalInstance()->start([fd = std::move(fd)]() mutable {
    // some work
    flush(std::move(fd)); // move the file descriptor ownership to flush()
});
