A CSS Transition

Fields

start_time: f64

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

delay: f64

The delay used for this transition.

property_animation: PropertyAnimation

The internal style PropertyAnimation for this transition.

state: AnimationState

The state of this transition.

is_new: bool

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

reversing_adjusted_start_value: AnimationValue

If this Transition has been replaced by a new one this field is used to help produce better reversed transitions.

reversing_shortening_factor: f64

If this Transition has been replaced by a new one this field is used to help produce better reversed transitions.

Implementations

impl Transition

fn new( start_time: f64, delay: f64, duration: f64, from: AnimationValue, to: AnimationValue, timing_function: &TimingFunction, ) -> Self

fn update_for_possibly_reversed_transition( &mut self, replaced_transition: &Transition, delay: f64, now: f64, )

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

Whether or not this animation has ended 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.

pub fn calculate_value(&self, time: f64) -> AnimationValue

Update the given animation at a given point of progress.

Trait Implementations

impl Clone for Transition

fn clone(&self) -> Transition

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Transition

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

Formats the value using the given formatter.

impl MallocSizeOf for Transition

fn size_of(&self, ops: &mut MallocSizeOfOps) -> usize

Measure the heap usage of all descendant heap-allocated structures, but not the space taken up by the value itself.
