A CSS Animation

Fields§

§name: Atom

The name of this animation as defined by the style.

§properties_changed: LonghandIdSet

The properties that change in this animation.

§computed_steps: Vec<ComputedKeyframe>

The computed style for each keyframe of this animation.

§started_at: f64

The time this animation started at, which is the current value of the animation timeline when this animation was created plus any animation delay.

§duration: f64

The duration of this animation.

§delay: f64

The delay of the animation.

§fill_mode: T

The animation-fill-mode property of this animation.

§iteration_state: KeyframesIterationState

The current iteration state for the animation.

§state: AnimationState

Whether this animation is paused.

§direction: T

The declared animation direction of this animation.

§current_direction: T

The current animation direction. This can only be normal or reverse.

§cascade_style: Arc<ComputedValues>

The original cascade style, needed to compute the generated keyframes of the animation.

§is_new: bool

Whether or not this animation is new and or has already been tracked by the script thread.

Implementations§

source§

impl Animation

source

fn is_cancelled_in_new_style(&self, new_style: &Arc<ComputedValues>) -> bool

Whether or not this animation is cancelled by changes from a new style.

source

pub fn iterate_if_necessary(&mut self, time: f64) -> bool

Given the current time, advances this animation to the next iteration, updates times, and then toggles the direction if appropriate. Otherwise does nothing. Returns true if this animation has iterated.

source

fn iterate(&mut self)

source

pub fn current_iteration_end_progress(&self) -> f64

A number (> 0 and <= 1) which represents the fraction of a full iteration that the current iteration of the animation lasts. This will be less than 1 if the current iteration is the fractional remainder of a non-integral iteration count.

source

pub fn current_iteration_duration(&self) -> f64

The duration of the current iteration of this animation which may be less than the animation duration if it has a non-integral iteration count.

source

fn iteration_over(&self, time: f64) -> bool

Whether or not the current iteration is over. Note that this method assumes that the animation is still running.

source

fn on_last_iteration(&self) -> bool

Assuming this animation is running, whether or not it is on the last iteration.

source

pub fn has_ended(&self, time: f64) -> bool

Whether or not this animation has finished at the provided time. This does not take into account canceling i.e. when an animation or transition is canceled due to changes in the style.

source

pub fn update_from_other(&mut self, other: &Self, now: f64)

Updates the appropiate state from other animation.

This happens when an animation is re-submitted to layout, presumably because of an state change.

There are some bits of state we can’t just replace, over all taking in account times, so here’s that logic.

source

fn get_property_declaration_at_time( &self, now: f64, map: &mut AnimationValueMap )

Fill in an AnimationValueMap with values calculated from this animation at the given time value.
