Enum PlaybackDirection 

pub enum PlaybackDirection {
    Forward,
    Backward,
}

Direction a tweening animation is playing.

The playback direction determines if the delta animation time passed to Tweenable::step() is added or subtracted to the current time position on the animation’s timeline.

• In Forward direction, time passes forward from t=0 to the total duration of the animation.
• Conversely, in Backward direction, time passes backward from the total duration back to t=0.

Note that backward playback is supported for infinite animations (when the repeat count is RepeatCount::Infinite), but Tweenable::rewind() is not supported and will panic.

Default: Forward.

Variants

Forward

Animation playing from start to end.

Backward

Animation playing from end to start, in reverse.

Implementations

impl PlaybackDirection

pub fn is_forward(&self) -> bool

Is the direction equal to PlaybackDirection::Forward?

pub fn is_backward(&self) -> bool

Is the direction equal to PlaybackDirection::Backward?

Trait Implementations

impl Clone for PlaybackDirection

fn clone(&self) -> PlaybackDirection

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for PlaybackDirection

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

Formats the value using the given formatter.

impl Default for PlaybackDirection

fn default() -> PlaybackDirection

Returns the “default value” for a type.

impl Not for PlaybackDirection

type Output = PlaybackDirection

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for PlaybackDirection

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