Struct ScrollPhysics 

pub struct ScrollPhysics { /* private fields */ }

Handles velocity estimation from input deltas, frame-rate-independent exponential decay, edge snapping, and animation state tracking.

Implementations

impl ScrollPhysics

pub fn new() -> ScrollPhysics

pub fn with_tuning( decay_per_60hz: f32, stop_velocity: f32, input_activate_velocity: f32, ) -> ScrollPhysics

pub fn record_user_input(&mut self, consumed: f32)

Feed a delta that arrived from real user input.

A first sample adopts its velocity outright, and a delta opposing an in-flight fling takes over from it. Both mirror Compose, where a new scroll(MutatePriority.UserInput) cancels the fling coroutine holding the MutatorMutex so the drag wins. Smoothing only applies between samples of one gesture: averaging up from zero on every frame would leave every flick at a fraction of its real speed.

pub fn record_nested_input(&mut self, consumed: f32)

Feed a delta that arrived as leftover from a nested child. Never takes over an in-flight fling: Compose’s dispatchRawDelta bypasses mutual exclusion precisely so a parent keeps coasting.

pub fn tick_integrate( &mut self, current: f32, min: f32, max: f32, ) -> Option<f32>

pub fn is_animating(&self) -> bool
