Scroll physics configuration for momentum scrolling

This controls how scrolling feels - the “weight” and “friction” of the scroll. Different platforms have different scroll physics (iOS vs Android vs Windows).

Fields

smooth_scroll_duration_ms: u32

Smooth scroll animation duration in milliseconds (default: 300ms) Only used when scroll-behavior: smooth

deceleration_rate: f32

Deceleration rate for momentum scrolling (0.0 = instant stop, 1.0 = never stops) Typical values: 0.95 (fast deceleration) to 0.998 (slow, iOS-like) Default: 0.95

min_velocity_threshold: f32

Minimum velocity threshold to start momentum scrolling (pixels/second) Below this, scrolling stops immediately. Default: 50.0

max_velocity: f32

Maximum scroll velocity (pixels/second). Default: 8000.0

wheel_multiplier: f32

Scroll wheel multiplier. Default: 1.0 Values > 1.0 make scrolling faster, < 1.0 slower

invert_direction: bool

Whether to invert scroll direction (natural scrolling). Default: false

overscroll_elasticity: f32

Overscroll elasticity (0.0 = no bounce, 1.0 = full bounce like iOS) Only applies when overscroll-behavior: auto. Default: 0.0 (no bounce)

max_overscroll_distance: f32

Maximum overscroll distance in pixels before rubber-banding stops Default: 100.0

bounce_back_duration_ms: u32

Bounce-back duration when releasing overscroll (milliseconds) Default: 400

Implementations

impl ScrollPhysics

pub const fn ios() -> Self

iOS-like scroll physics with momentum and bounce

pub const fn macos() -> Self

macOS-like scroll physics

pub const fn windows() -> Self

pub const fn android() -> Self

Android-like scroll physics

Trait Implementations

impl Clone for ScrollPhysics

fn clone(&self) -> ScrollPhysics

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollPhysics

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

Formats the value using the given formatter.

impl Default for ScrollPhysics

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for ScrollPhysics

fn eq(&self, other: &ScrollPhysics) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for ScrollPhysics

fn partial_cmp(&self, other: &ScrollPhysics) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
