Struct tokio::runtime::time::handle::Handle

pub(crate) struct Handle {
    pub(super) time_source: TimeSource,
    pub(super) inner: Inner,
}

Handle to time driver instance.

Fields

time_source: TimeSource

inner: Inner

Implementations

impl Handle

pub(crate) fn time_source(&self) -> &TimeSource

Returns the time source associated with this handle.

pub(super) fn is_shutdown(&self) -> bool

Checks whether the driver has been shutdown.

pub(crate) fn unpark(&self)

Track that the driver is being unparked

impl Handle

fn process(&self, clock: &Clock)

Runs timer related logic, and returns the next wakeup time

fn process_at_time(&self, now: u64)

unsafe fn clear_entry(&self, entry: NonNull<TimerShared>)

Removes a registered timer from the driver.

The timer will be moved to the cancelled state. Wakers will not be invoked. If the timer is already completed, this function is a no-op.

This function always acquires the driver lock, even if the entry does not appear to be registered.

SAFETY: The timer must not be registered with some other driver, and add_entry must not be called concurrently.

unsafe fn reregister( &self, unpark: &IoHandle, new_tick: u64, entry: NonNull<TimerShared> )

Removes and re-adds an entry to the driver.

SAFETY: The timer must be either unregistered, or registered with this driver. No other threads are allowed to concurrently manipulate the timer at all (the current thread should hold an exclusive reference to the TimerEntry)

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
