Implementations

impl TimerFd

pub fn new(status: FileStatus) -> Arc<AtomicRefCell<Self>>

Creates a new TimerFd object that internally sets up a Timer that can be waited on with poll, select, and epoll, enabling support for timerfd_create(2).

We wrap the new TimerFd in an Arc<AtomicRefCell> because we need to use a weak reference to internally support setting up callback functions that reference the TimerFd on timer expiration.

pub fn get_timer_remaining(&self) -> Option<SimulationTime>

Returns the relative duration until the next expiration event occurs if the timer is armed, and None if the timer is disarmed.

pub fn get_timer_interval(&self) -> Option<SimulationTime>

Returns the relative duration over which the timer has been configured to periodically expire, or None if the timer is configured to expire only once.

pub fn arm_timer( &mut self, host: &Host, expire_time: EmulatedTime, interval: Option<SimulationTime>, cb_queue: &mut CallbackQueue, )

Arm the timer by setting its expiration time and interval, enabling support for timerfd_settime(2). The readable state of the TimerFd is updated as appropriate.

pub fn disarm_timer(&mut self, cb_queue: &mut CallbackQueue)

Disarm the timer so that it no longer fires expiration events, enabling support for timerfd_settime(2). The readable state of the TimerFd is updated as appropriate.
