Struct base::timer::Timer

pub struct Timer {
    pub(crate) handle: SafeDescriptor,
    pub(crate) interval: Option<Duration>,
}

Fields

handle: SafeDescriptor

interval: Option<Duration>

Implementations

impl Timer

pub fn try_clone(&self) -> Result<Timer, Error>

Creates a new Timer instance that shares the same underlying SafeDescriptor as the existing Timer instance.

impl Timer

pub fn new() -> Result<Timer>

Creates a new timerfd. The timer is initally disarmed and must be armed by calling reset.

fn set_time( &mut self, dur: Option<Duration>, interval: Option<Duration> ) -> Result<()>

Trait Implementations

impl AsRawDescriptor for Timer

fn as_raw_descriptor(&self) -> RawDescriptor

Returns the underlying raw descriptor.

impl AsRawFd for Timer

fn as_raw_fd(&self) -> RawFd

Extracts the raw file descriptor.

impl FromRawDescriptor for Timer

unsafe fn from_raw_descriptor(handle: RawDescriptor) -> Self

Safety

impl IntoRawDescriptor for Timer

fn into_raw_descriptor(self) -> RawDescriptor

impl TimerTrait for Timer

fn reset_oneshot(&mut self, dur: Duration) -> Result<()>

Sets the timer to expire after dur without repeating. Cancels any existing timer.

fn reset_repeating(&mut self, dur: Duration) -> Result<()>

Sets the timer to fire repeatedly at dur intervals. Cancels any existing timer.

fn clear(&mut self) -> Result<()>

Disarms the timer.

fn wait(&mut self) -> Result<()>

Waits until the timer expires.

fn mark_waited(&mut self) -> Result<bool>

After a timer is triggered from an EventContext, mark the timer as having been waited for. If a timer is not marked waited, it will immediately trigger the event context again. This does not need to be called after calling Timer::wait.

fn resolution(&self) -> Result<Duration>

Returns the resolution of timers on the host.
