Struct SceneUpdates 

pub struct SceneUpdates<'a> {
    pub content: &'a [NodeId],
    pub layers: &'a [NodeId],
    pub moved: &'a [NodeId],
}

Describes scene nodes whose recorded content or layer properties changed.

Content updates may re-record a node’s draw commands. Layer updates change graphics-layer properties while retaining those recordings. If a node appears in both slices, content dirt takes precedence. Layout, child structure, and draw-command changes belong in content.

use cranpose_render_common::SceneUpdates;
let updates = SceneUpdates {
    content: &[1],
    layers: &[2],
    moved: &[3],
};
assert!(!updates.is_empty());

Fields

content: &'a [NodeId]

Nodes whose recorded draw content must be refreshed.

layers: &'a [NodeId]

Nodes whose graphics-layer properties changed without content dirt.

moved: &'a [NodeId]

Nodes that moved in their parent and kept their size: the scene moves what it drew for them unless another list names them too.

Implementations

impl<'a> SceneUpdates<'a>

pub const fn content(nodes: &'a [NodeId]) -> Self

Creates an update containing only nodes with changed draw content.

pub const fn is_empty(self) -> bool

Returns whether the update contains no dirty nodes.
