Struct LiquidDynamics 

pub struct LiquidDynamics { /* private fields */ }

Per-lens frame integrator. Interior-mutable so per-frame draw closures (plain Fn) can advance it without a RefCell dance.

Implementations

impl LiquidDynamics

pub fn new(runtime: RuntimeHandle) -> Self

pub fn reset(&self)

Forget all motion state (fresh grab, teleporting relayout): the next update re-anchors at rest.

pub fn update(&self, pos: (f32, f32)) -> LiquidPose

Advance with the lens ride position using the runtime’s animation clock. Multiple reads within one frame return the same pose.

pub fn advance(&self, pos: (f32, f32), dt: f32) -> LiquidPose

Pure integration step (exposed for tests and custom clocks): advance by dt seconds toward pos.

pub fn pose(&self) -> LiquidPose

Latest pose without advancing.
