Struct ContinuousWithMomentum 

pub struct ContinuousWithMomentum { /* private fields */ }

Continuous momentum with friction-based deceleration

The position continues moving with the release velocity and gradually slows down due to friction. Good for free-scrolling content.

Example

let mut behavior = ContinuousWithMomentum::new();
behavior.set_friction(0.08); // Higher = more friction

Implementations

impl ContinuousWithMomentum

pub const fn new() -> Self

Create a new continuous momentum behavior

pub fn friction(self, friction: f64) -> Self

Set the friction that damps movement

Typical values are 0.05-0.15. Higher = more friction = stops faster.

pub const fn minimum_velocity(self, min_vel: f64) -> Self

Set the minimum velocity threshold

When velocity drops below this, animation stops. Default is 0.05.

pub const fn velocity(&self) -> f64

Get the current velocity

Trait Implementations

impl Clone for ContinuousWithMomentum

fn clone(&self) -> ContinuousWithMomentum

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ContinuousWithMomentum

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ContinuousWithMomentum

fn default() -> Self

Returns the “default value” for a type.

impl MomentumBehavior for ContinuousWithMomentum

fn released_with_velocity(&mut self, _position: f64, velocity: f64)

Called when the drag is released with a velocity (units per second)

fn next_position(&mut self, current_position: f64, elapsed_seconds: f64) -> f64

Get the next position after elapsed time This should also update internal state (like decaying velocity)

fn is_stopped(&self, _position: f64) -> bool

Check if the animation has stopped
