Struct TimerQueueItem 

#[repr(align(8))]
pub struct TimerQueueItem { /* private fields */ }

The timer queue item provided by the executor.

This type is opaque, it only provides the raw storage for a queue item. The queue implementation is responsible for reinterpreting the contents of the item using TimerQueueItem::as_ref and TimerQueueItem::as_mut.

Implementations

impl TimerQueueItem

pub const fn new() -> Self

Creates a new, zero-initialized TimerQueueItem.

pub unsafe fn from_embassy_waker(waker: &Waker) -> &'static mut Self

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 as_ref<T>(&self) -> &T

Access the data as a reference to a type T.

Safety:

• The type must be valid when zero-initialized.
• The timer queue should only be interpreted as a single type T during its lifetime.

pub unsafe fn as_mut<T>(&self) -> &mut T

Access the data as a reference to a type T.

Safety:

• The type must be valid when zero-initialized.
• The timer queue should only be interpreted as a single type T during its lifetime.
