Struct PollSet 

pub struct PollSet(/* private fields */);

A data structure for waking up tasks that are waiting for I/O events.

Implementations

impl PollSet

pub const fn new() -> Self

Creates a new empty PollSet.

pub unsafe fn register(&self, waker: &Waker, interests: IoEvents)

Registers a waker for the requested I/O events.

Safety

This method is task/deferred-context only. Callers must not invoke it from hard IRQ, NMI, or trap callbacks, and must not hold locks that may be re-entered by the registered waker or by poll wakeup paths.

pub unsafe fn wake(&self, ready: IoEvents) -> usize

Wakes up registered wakers whose interests intersect ready.

Safety

This method is task/deferred-context only. Callers must not invoke it from hard IRQ, NMI, or trap callbacks. The readiness state represented by ready must be published before this method is called, and callers must not hold locks that may be re-entered by waker execution or poll wakeup paths.

pub fn wake_from_irq(&self, ready: IoEvents) -> usize

Wakes up registered wakers whose interests intersect ready from IRQ context.

Unlike wake, this does not allocate a replacement waiter buffer. It drains the already-initialized entries in place, so device IRQ handlers can acknowledge the device and then wake matching poll waiters without allocating in hard IRQ context.

Trait Implementations

impl Default for PollSet

fn default() -> Self

Returns the “default value” for a type.

impl Drop for PollSet

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
