Struct ScrollClock 

pub struct ScrollClock { /* private fields */ }

A Clock implementation backed by scroll-position changes.

Each call to set_scroll stores a normalised delta; the next call to Clock::delta consumes and returns it.

Example

use animato_driver::{Clock, AnimationDriver};
use animato_driver::scroll::ScrollClock;

let mut clock = ScrollClock::new(0.0, 1000.0);
clock.set_scroll(250.0);
let dt = clock.delta(); // ≈ 0.25
assert!((dt - 0.25).abs() < 0.001);

Implementations

impl ScrollClock

pub fn new(min: f32, max: f32) -> Self

Create a scroll clock spanning [min, max].

pub fn set_scroll(&mut self, pos: f32)

Register a new scroll position and accumulate the normalised delta.

Multiple calls before Clock::delta accumulate (they do not cancel each other out — only magnitudes are summed).

pub fn scroll_position(&self) -> f32

Current scroll position in user units.

pub fn progress(&self) -> f32

Normalised scroll progress ∈ [0.0, 1.0].

Trait Implementations

impl Clock for ScrollClock

fn delta(&mut self) -> f32

Returns the accumulated normalised delta since the last call.

impl Clone for ScrollClock

fn clone(&self) -> ScrollClock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ScrollClock

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

Formats the value using the given formatter.

impl Default for ScrollClock

fn default() -> Self

Returns the “default value” for a type.
