Struct TimerQueue 

pub struct TimerQueue { /* private fields */ }

Timer queue managing a set of timers using a BinaryHeap.

Timers are ordered by their fire_date for efficient expiration checking. Repeating timers are automatically rearmed after firing.

Implementations

impl TimerQueue

pub fn new() -> Self

Create a new empty TimerQueue

pub fn schedule(&mut self, timer_id: TimerId)

Schedule a timer for future firing

Arguments

• timer_id - The ID of the timer to schedule

pub fn reschedule(&mut self, timer_id: TimerId)

Reschedule an existing timer

Arguments

• timer_id - The ID of the timer to reschedule

pub fn invalidate(&mut self, timer_id: TimerId)

Invalidate (disarm) a timer

Arguments

• timer_id - The ID of the timer to invalidate

pub fn fire_expired(&mut self) -> Vec<(TimerId, bool)>

Fire all expired timers

Returns a list of (timer_id, autoclose) for timers that fired

pub fn nextfire_delay(&self) -> Option<f64>

Get the time until the next timer fires

Returns None if no timers are armed

pub fn clear(&mut self)

Clear all timers

pub fn add_timer(&mut self, timer: EngineBaseTimer) -> TimerId

Add a timer to the queue

Returns the TimerId for the new timer

pub fn remove_timer(&mut self, timer_id: TimerId)

Remove a timer by ID

pub fn armed_count(&self) -> usize

Get the number of armed timers

pub fn update_time(&mut self, time: f64)

Update the current time (should be called before fire_expired)

pub fn is_valid(&self, timer_id: TimerId) -> bool

Check if a timer is valid
