Struct PingPong 

pub struct PingPong<Source> { /* private fields */ }

A finite forward/backward cycle produced by Animation::ping_pong.

Trait Implementations

impl<Value, Source: Animation<Value>> Animation<Value> for PingPong<Source>

fn sample(&self, time: Time) -> Value

Samples without advancing a clock or changing playback state.

fn duration(&self) -> Option<Duration>

Returns the finite duration, or None for an unbounded signal.

fn map<Output, Function>(self, function: Function) -> Map<Self, Function, Value>

where Self: Sized, Function: Fn(Value) -> Output + Send + Sync,

Transforms values without changing timing.

fn zip<OtherValue, Other>(self, other: Other) -> Zip<Self, Other>

where Self: Sized, Other: Animation<OtherValue>,

Samples in parallel; the duration is infinite if either input is infinite.

fn delay(self, offset: Duration) -> Delay<Self>

where Self: Sized,

Delays a finite animation, holding its initial value before the offset. Infinite signals shift their signed time instead. Negative offsets and finite duration overflow panic at construction.

fn speed(self, factor: f64) -> Speed<Self>

where Self: Sized,

Changes playback speed by a finite, strictly positive factor. Durations round to the nearest tick; a collapsed finite animation becomes instantaneous. Invalid factors and unrepresentable durations panic.

fn then<Next: Animation<Value>>(self, next: Next) -> Then<Self, Next>

where Self: Sized,

Runs two finite animations in sequence. The second owns their shared boundary. Infinite sources or duration overflow panic at construction.

fn reverse(self) -> Reverse<Self>

where Self: Sized,

Reverses a finite animation. Infinite sources panic at construction.

fn repeat(self, count: u32) -> Repeat<Self>

where Self: Sized,

Plays a finite animation count times. Intermediate boundaries restart; the final boundary holds the target. Zero repeats hold the initial value. Infinite sources or duration overflow panic at construction.

fn ping_pong(self) -> PingPong<Self>

where Self: Sized,

Plays a finite animation forward then backward, ending at its initial value. Infinite sources or duration overflow panic at construction.

fn boxed(self) -> Arc<dyn Animation<Value>>

where Self: Sized + 'static,

Shares a type-erased animation, retaining sampling and combinators.

impl<Source: Clone> Clone for PingPong<Source>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Source: Debug> Debug for PingPong<Source>

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

Formats the value using the given formatter.
