Enum NodeUpdate 

pub enum NodeUpdate {
    Content,
    Draws,
    Layer,
    Moved,
    MovedLayer,
}

What changed in a node since the scene last drew it, and so how the scene updates what it drew for that node.

Variants

Content

Its layout, children or draw commands changed: the scene records it again.

Draws

Only state its draws read changed: its layer keeps its children and records the node’s draws again.

Layer

Its graphics-layer properties changed and it drew the same.

Moved

It moved in its parent and kept its size: its layer moves and keeps what it drew.

MovedLayer

It moved and its layer properties changed: its layer moves, takes the new properties and keeps what it drew.

Implementations

impl NodeUpdate

pub fn merge(self, other: Self) -> Self

The update a node named with both self and other needs: content wins over the others, draws with any other change need the content, and a move with a layer change moves the layer with its new properties.
