Struct AsyncPoll

pub struct AsyncPoll { /* private fields */ }

Available on crate features unix and poll-driver only.

An unsafe asynchronous poller around a pollfd.

See AsyncPoll::new.

Implementations

impl AsyncPoll

pub unsafe fn new(descriptor: pollfd) -> Result<AsyncPoll, Errno>

Construct a new poll handle around the given pollfd, registering it for interest in receiving events asynchronously.

Dropping the returned handle will unregister interest.

Panics

Panics unless an audio runtime is available.

See Runtime.

Safety

This is unsafe, because the caller must ensure that the provided pollfd is not closed before this handle is dropped.

pub async fn returned_events(&self) -> PollEventsGuard<'_>

Wait for events to be triggered on the background driver and return a guard to the events.

Once this guard is dropped the driver will be released to register more interest.

Trait Implementations

impl Drop for AsyncPoll

fn drop(&mut self)
