Struct AnimSpec 

pub struct AnimSpec {
    pub keyframes: Vec<Keyframe>,
    pub enter: Option<Enter>,
    pub exit: Option<Enter>,
}

Per-node animation declarations. Boxed on NodeSpec: enter and exit are 60 bytes each and almost every node has neither.

Fields

keyframes: Vec<Keyframe>

CSS-style stops for the animatable slots (see crate::keyframes): with a transition, the slots a stop names cycle through the stops over the transition’s duration, in its repeat direction, offset by its delay_ms — forever, and without the view redrawing. Slots no stop names still tween toward what the view declares. Empty = none.

enter: Option<Enter>

Where this node’s slots start the first frame it is seen (see crate::enter): with a transition, the slots it names ease in from there instead of snapping — dx/dy slide the node in from that far away, bg fades it in. A node that vanishes and returns enters again. None = first sight snaps.

exit: Option<Enter>

Where this node’s slots end the frame after the view stops declaring it (see crate::depart). An exit is an Enter read the other way: with a transition, the departing subtree is copied out of the last frame that had it and replayed — frozen where layout left it, on top, inert — while the slots this names ease from where they were toward what it declares. Needs a stable key across frames, and a transition with a duration; without both, a removed node vanishes at once as it always did.

Implementations

impl AnimSpec

pub const EMPTY: AnimSpec

The group as a node that declares none of it — what NodeSpec’s accessor hands back when the box is None.
