Struct riddle_time::TimeSystemHandle

pub struct TimeSystemHandle { /* fields omitted */ }

Implementations

impl TimeSystemHandle

pub fn downgrade(this: &TimeSystemHandle) -> TimeSystemWeak

Downgrade this handle to a weak handle

pub fn eq(a: &TimeSystemHandle, b: &TimeSystemHandle) -> bool

Test whether two handles point to the same location in memory

Methods from Deref<Target = TimeSystem>

pub fn fps(&self) -> f32

Get the current FPS as calculated based on previous frame durations.

pub fn delta_secs(&self) -> f32

Get the current delta t as calculated based on previous frame durations.

pub fn frame_instant(&self) -> Instant

Get the reference time for this frame. Captured during ext::TimeSystemExt::process_frame.

pub fn register_timer<F>(&self, duration: Duration, callback: F) -> TimerHandle where
    F: FnOnce() + Send + 'static, 

Register a timer with a callback which will be fired when the time elpases.

The returned handle may be dropped without cancelling the timer.

Example

let val = Arc::new(AtomicBool::new(false));

time_system.register_timer(std::time::Duration::from_millis(200), {
    let val = val.clone();
    move || { val.store(true, Ordering::Relaxed); }
});

// A while later
assert_eq!(true, val.load(Ordering::Relaxed));
