Enum TimelineStep 

pub enum TimelineStep {
    Track(Track),
    Sequence(Sequence),
    Parallel(Parallel),
    Hold(Hold),
}

A timeline step that can contribute duration to a timeline.

Variants

Track(Track)

A keyframe track.

Sequence(Sequence)

A sequential group of steps.

Parallel(Parallel)

A parallel group of steps.

Hold(Hold)

A silent hold segment.

Implementations

impl TimelineStep

pub fn total_duration(&self) -> Option<Duration>

Returns the finite total duration of this step, or None for infinite tracks.

pub fn sample_at(&self, offset: impl Into<Duration>) -> Option<PropertySnapshot>

Samples this step at local timeline offset.

pub fn completion_snapshot(&self) -> Option<PropertySnapshot>

Samples the final visual state for this step.

Trait Implementations

impl Clone for TimelineStep

fn clone(&self) -> TimelineStep

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TimelineStep

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

Formats the value using the given formatter.

impl From<Hold> for TimelineStep

fn from(value: Hold) -> Self

Converts to this type from the input type.

impl From<Parallel> for TimelineStep

fn from(value: Parallel) -> Self

Converts to this type from the input type.

impl From<Sequence> for TimelineStep

fn from(value: Sequence) -> Self

Converts to this type from the input type.

impl From<Track> for TimelineStep

fn from(value: Track) -> Self

Converts to this type from the input type.

impl PartialEq for TimelineStep

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