§has_running_animations: Cell<bool>

Whether or not we have animations that are running.

§rooted_nodes: DomRefCell<FxHashMap<OpaqueNode, Dom<Node>>>

§pending_events: DomRefCell<Vec<TransitionOrAnimationEvent>>

A list of pending animation-related events.

Implementations§

source§

impl Animations

source

pub(crate) fn new() -> Self

source

pub(crate) fn clear(&self)

source

pub(crate) fn mark_animating_nodes_as_dirty(&self)

source

pub(crate) fn update_for_new_timeline_value(&self, window: &Window, now: f64)

source

pub(crate) fn cancel_animations_for_node(&self, node: &Node)

Cancel animations for the given node, if any exist.

source

pub(crate) fn do_post_reflow_update(&self, window: &Window, now: f64)

Processes any new animations that were discovered after reflow. Collect messages that trigger events for any animations that changed state.

source

fn update_running_animations_presence(&self, window: &Window, new_value: bool)

source

fn handle_animation_presence_or_pending_events_change(&self, window: &Window)

source

pub(crate) fn running_animation_count(&self) -> usize

source

fn start_pending_animations(
    &self,
    key: &AnimationSetKey,
    set: &mut ElementAnimationSet,
    now: f64,
    pipeline_id: PipelineId
)

Walk through the list of pending animations and start all of the ones that have left the delay phase.

source

fn finish_running_animations(
    &self,
    key: &AnimationSetKey,
    set: &mut ElementAnimationSet,
    now: f64,
    pipeline_id: PipelineId
)

Walk through the list of running animations and remove all of the ones that have ended.

source

fn handle_canceled_animations(
    &self,
    key: &AnimationSetKey,
    set: &mut ElementAnimationSet,
    now: f64,
    pipeline_id: PipelineId
)

Send events for canceled animations. Currently this only handles canceled transitions, but eventually this should handle canceled CSS animations as well.

source

fn handle_new_animations(
    &self,
    key: &AnimationSetKey,
    set: &mut ElementAnimationSet,
    now: f64,
    pipeline_id: PipelineId
)

source

fn root_newly_animating_dom_nodes(
    &self,
    sets: &FxHashMap<AnimationSetKey, ElementAnimationSet>
)

Ensure that all nodes with new animations are rooted. This should be called immediately after a restyle, to ensure that these addresses are still valid.

source

fn unroot_unused_nodes(
    &self,
    sets: &FxHashMap<AnimationSetKey, ElementAnimationSet>
)

source

fn add_transition_event(
    &self,
    key: &AnimationSetKey,
    transition: &Transition,
    event_type: TransitionOrAnimationEventType,
    now: f64,
    pipeline_id: PipelineId
)

source

fn add_animation_event(
    &self,
    key: &AnimationSetKey,
    animation: &Animation,
    event_type: TransitionOrAnimationEventType,
    now: f64,
    pipeline_id: PipelineId
)

source

pub(crate) fn send_pending_events(&self, window: &Window)
