A Signal with a nonnegative, stable duration.

Finite animations hold their endpoint values outside [0, duration]. Sequencing combinators exist only here, so an unbounded signal cannot be delayed, sequenced or repeated by construction.

Required Methods

fn duration(&self) -> Duration

Returns the nonnegative duration.

Provided Methods

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

where Self: Sized,

Delays the animation, holding its initial value before the offset.

Panics

Panics on duration overflow; see Self::try_delay.

fn try_delay(self, offset: Duration) -> Result<Delay<Self>, ValidationError>

where Self: Sized,

Delays like Self::delay, reporting duration overflow.

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 animation becomes instantaneous.

Panics

Panics for an invalid factor or unrepresentable duration; see Self::try_speed.

fn try_speed(self, factor: f64) -> Result<Speed<Self>, ValidationError>

where Self: Sized,

Changes speed like Self::speed, reporting an invalid factor or unrepresentable duration.

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

where Self: Sized,

Runs two animations in sequence. The second owns their shared boundary. Duration overflow panics at construction.

fn reverse(self) -> Reverse<Self>

where Self: Sized,

Reverses the animation.

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

where Self: Sized,

Plays the animation count times. Intermediate boundaries restart; the final boundary holds the target. Zero repeats hold the initial value. Duration overflow panics at construction.

fn ping_pong(self) -> PingPong<Self>

where Self: Sized,

Plays the animation forward then backward, ending at its initial value. Duration overflow panics at construction.

fn boxed_finite(self) -> Arc<dyn FiniteAnimation<Value>>

where Self: Sized + 'static,

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

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
