Struct egui::MovementTracker

pub struct MovementTracker<T> { /* fields omitted */ }

This struct tracks recent values of some time series. This can be used for things like smoothed averages (for e.g. FPS) or for smoothed velocity (e.g. mouse pointer speed). All times are in seconds.

Implementations

impl<T> MovementTracker<T> where
    T: Copy, 

pub fn new(max_len: usize, max_age: f64) -> Self

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

pub fn dt(&self) -> f32

Amount of time contained from start to end in this MovementTracker

pub fn values<'a>(&'a self) -> impl Iterator<Item = T> + 'a

pub fn clear(&mut self)

pub fn add(&mut self, now: f64, value: T)

Values must be added with a monotonically increasing time, or at least not decreasing.

pub fn mean_time_interval(&self) -> Option<f32>

Mean time difference between values in this MovementTracker.

pub fn flush(&mut self, now: f64)

Remove samples that are too old

impl<T> MovementTracker<T> where
    T: Copy,
    T: Sum,
    T: Div<f32, Output = T>, 

pub fn sum(&self) -> T

pub fn average(&self) -> Option<T>

impl<T, Vel> MovementTracker<T> where
    T: Copy,
    T: Sub<Output = Vel>,
    Vel: Div<f32, Output = Vel>, 

pub fn velocity(&self) -> Option<Vel>

Calculate a smooth velocity (per second) over the entire time span
