Struct KEvent 

Source 
pub struct KEvent { /* private fields */ }
Expand description

A wrapper around Zircon’s C++ Event.

Implementations§

Source§

impl KEvent

Source

pub fn project<'__pin>(self: Pin<&'__pin mut Self>) -> KEventProjection<'__pin>

Pin-projects all fields of Self.

These fields are structurally pinned:

  • raw

These fields are not structurally pinned:

Source§

impl KEvent

Source

pub fn init(initial: bool) -> impl PinInit<Self, Infallible>

Creates a new KEvent with the given initial signaled state.

Source

pub fn signal(&self)

Signals the event.

Wakes up all waiting threads.

Source

pub fn signal_etc(&self, status: Status)

Signals the event with a specific status.

Source

pub fn unsignal(&self)

Unsignals the event.

Source

pub fn wait(&self) -> Result<(), Status>

Waits for the event to be signaled.

Returns Ok(()) if signaled, or an error status.

Source

pub fn wait_deadline(&self, deadline: zx_instant_mono_t) -> Result<(), Status>

Waits for the event to be signaled with a deadline.
