Struct TimerQueueItemProviderImpl 

pub struct TimerQueueItemProviderImpl;

The global TimerQueueItemProvider implementation.

Implementations

impl TimerQueueItemProviderImpl

pub unsafe fn item_from_waker(waker: &Waker) -> &'static mut TimerQueueItem

Retrieves the TimerQueueItem reference that belongs to the task of the waker.

Panics if called with a non-embassy waker.

Safety

The caller must ensure they are not violating Rust’s aliasing rules - it is not allowed to use this method to create multiple mutable references to the same TimerQueueItem at the same time.

This function must only be called in the context of a timer queue implementation.

pub unsafe fn try_item_from_waker( waker: &Waker, ) -> Option<&'static mut TimerQueueItem>

Like item_from_waker, but returns None instead of panicking if the waker is not an embassy waker.

Safety

Same as item_from_waker.
