enum class QtFuture::Launch
Represents execution policies for running a QFuture continuation.
Constant | Value | Description |
---|---|---|
QtFuture::Launch::Sync | 0 | The continuation will be launched in the same thread that fulfills the promise associated with the future to which the continuation was attached, or if it has already finished, the continuation will be invoked immediately, in the thread that executes then() . |
QtFuture::Launch::Async | 1 | The continuation will be launched in a separate thread taken from the global QThreadPool. |
QtFuture::Launch::Inherit | 2 | The continuation will inherit the launch policy or thread pool of the future to which it is attached. |
Sync
is used as a default launch policy.
This enum was introduced in Qt 6.0.
