pub fn reset(&mut self)

Resets the tween to the beginning.

pub fn has_completed(&self) -> bool

Returns true if the tween has completed.

pub fn apply(&mut self, time_advance: f32) -> f32

Returns the new value after applying the tween, advancing time by time_advance.

pub fn reverse(&mut self)

Reverses the tween, adjusting the current time position such that it will retrace its steps so far.

pub fn current_time(&self) -> f32

Returns the current time position of the tween.

pub fn start_value(&self) -> f32

Returns the starting value of the tween.

pub fn end_value(&self) -> f32

Returns the ending value of the tween.

pub fn duration(&self) -> f32
