Struct KeyframesAnimation 

pub struct KeyframesAnimation {
    pub steps: Vec<KeyframesStep>,
    pub steps_with_range_name: Vec<KeyframesStep>,
    pub properties_changed: PropertyDeclarationIdSet,
    pub vendor_prefix: Option<VendorPrefix>,
}

This structure represents a list of animation steps computed from the list of keyframes, in order.

It only takes into account animable properties.

Fields

steps: Vec<KeyframesStep>

The different steps of the animation.

steps_with_range_name: Vec<KeyframesStep>

The different steps of the animation. Those steps are only for keyframe selectors with timeline range names. We intentionally use a different vector because it is unsorted and we would like to maintain its specified order when grouping them. Also, per spec, the computed order requires us to pull percentage-only keyframes to the front and sort them, so using a separate vector makes it easier to group them to maintain the computed order. https://drafts.csswg.org/css-animations-2/#keyframe-processing https://github.com/w3c/csswg-drafts/issues/8507

properties_changed: PropertyDeclarationIdSet

The properties that change in this animation.

vendor_prefix: Option<VendorPrefix>

Vendor prefix type the @keyframes has.

Implementations

impl KeyframesAnimation

pub fn from_keyframes( keyframes: &[Arc<Locked<Keyframe>>], vendor_prefix: Option<VendorPrefix>, guard: &SharedRwLockReadGuard<'_>, ) -> Self

Create a keyframes animation from a given list of keyframes.

This will return a keyframe animation with empty steps and properties_changed if the list of keyframes is empty, or there are no animated properties obtained from the keyframes.

Otherwise, this will compute and sort the steps used for the animation, and return the animation object.

Trait Implementations

impl Clone for KeyframesAnimation

fn clone(&self) -> KeyframesAnimation

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for KeyframesAnimation

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

Formats the value using the given formatter.

impl MallocSizeOf for KeyframesAnimation

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.
