Struct leak_playground_std::thread::JoinGuard

source ·
pub struct JoinGuard<'a, T> {
    child: ManuallyDrop<JoinHandle<T>>,
    _borrow: Unforget<'static, PhantomData<&'a ()>>,
    _unsend: PhantomData<*mut ()>,
}
Expand description

Handle to a thread, which joins on drop.

Cannot be sent across threads. This is made to ensure we won’t put this into itself, thus forgetting it.

To spawn use spawn_scoped.

Fields§

§child: ManuallyDrop<JoinHandle<T>>§_borrow: Unforget<'static, PhantomData<&'a ()>>

Not sure about covariance there.

§_unsend: PhantomData<*mut ()>
