Struct AnimatingImages 

pub struct AnimatingImages {
    pub node_to_state_map: FxHashMap<OpaqueNode, ImageAnimationState>,
    pub dirty: bool,
}

Fields

node_to_state_map: FxHashMap<OpaqueNode, ImageAnimationState>

A map from the OpaqueNode to the state of an animating image. This is used to update frames in script and to track newly animating nodes.

dirty: bool

Whether or not this map has changed during a layout. This is used by script to trigger future animation updates.
