Struct Bezier 

pub struct Bezier(pub f64, pub f64, pub f64, pub f64);

Cubic bezier easing curve.

Defined by two control points (x1, y1) and (x2, y2) that shape the curve. The curve starts at (0, 0) and ends at (1, 1).

Tuple Fields

0: f64

1: f64

2: f64

3: f64

Implementations

impl Bezier

pub const fn ease() -> Self

Standard ease curve - slow start and end, fast middle.

pub const fn ease_in() -> Self

Ease-in curve - slow start, fast end.

pub const fn ease_out() -> Self

Ease-out curve - fast start, slow end.

pub const fn ease_in_out() -> Self

Ease-in-out curve - slow start and end.

pub fn eval(&self, time: f64) -> f64

Evaluates the bezier curve at the given time.

Trait Implementations

impl Clone for Bezier

fn clone(&self) -> Bezier

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Bezier

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

Formats the value using the given formatter.

impl Default for Bezier

fn default() -> Bezier

Returns the “default value” for a type.

impl Easing for Bezier

fn eval(&self, time: f64) -> f64

Evaluates the easing function at the given time.

fn velocity(&self, time: f64) -> Option<f64>

Returns the velocity at the given time, if available.

fn finished(&self, time: f64) -> bool

Returns whether the animation has finished at the given time.

impl PartialEq for Bezier

fn eq(&self, other: &Bezier) -> 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.
