Implementations§

source§

impl Notifier

source

pub unsafe fn notify(&self, notification: NonZeroU32) -> (bool, bool)

§Safety

This method is unsafe because it is possible to call core::mem::forget on the Monitor instance that produced this notifier.

If that happens, the Drop dtor of Monitor will NOT be called, which - in turn - means that the Arc holding the task reference will stick around even when the actual task where the Monitor instance was created no longer exists. Which - in turn - would mean that the method will be trying to notify a task which does no longer exist, which would lead to UB and specifically - to memory corruption.
