Struct EasingTime

source
pub struct EasingTime(/* private fields */);
Expand description

Easing function input.

An easing function converts this time into a EasingStep factor.

The time is always in the [0..=1] range, factors are clamped to this range on creation.

Implementations§

source§

impl EasingTime

source

pub fn new(factor: Factor) -> Self

New from Factor.

The factor is clamped to the [0..=1] range.

source

pub fn elapsed( duration: Duration, elapsed: Duration, time_scale: Factor, ) -> Self

New easing time from total duration, elapsed time and time_scale.

If elapsed >= duration the time is 1.

source

pub fn start() -> Self

Gets the start time, zero.

source

pub fn end() -> Self

Gets the end time, one.

source

pub fn is_start(self) -> bool

If the time represents the start of the animation.

source

pub fn is_end(self) -> bool

If the time represents the end of the animation.

source

pub fn fct(self) -> Factor

Get the time as a Factor.

source

pub fn pct(self) -> FactorPercent

Get the time as a FactorPercent.

source

pub fn reverse(self) -> Self

Flip the time.

Returns 1 - self.
